1. ING Instrumentation in Semester 2005A

William Herschel Telescope

For an overview of the proposal submission process and current 
instrumentation at ING, see

WHT applicants are encouraged to submit proposals for larger 
time applications. For the UK community, the PATT2 application 
form allows a 2-page scientific justification for WHT proposals 
which are for *eight* or more nights, or are long-term (multi-
semester) or are coordinated with other telescopes.

The following instrument/detector configurations are available:

Instrument         Detector       Comments
ISIS BLUE          EEV12
AUX-port imager    TEK1
Prime Focus Camera 2xEEV Mosaic
AUTOFIB2/WYFFOS    2xEEV Mosaic   Long camera, shared risks
NAOMI/INGRID       1kx1k HgCdTe
NAOMI/OASIS        2kx4k MIT/LL   Shared risks
LIRIS              1kx1k HgCdTe   Shared risks

Adaptive Optics
All AO observations are carried out in queue mode by ING
staff. Applicants for AO observations are encouraged to consult 
the NAOMI instrument home page for more information about 
individual instruments and about AO performance:

Visitor Instruments
Applicants wishing to submit proposals to use an established visitor 
instrument on the WHT should contact the relevant Instrument Contact 
in the first instance; WHT visitor instruments and contacts are:

INTEGRAL    Evencio Mediavilla,
[INTEGRAL is available with the WYFFOS long-camera only]

PN.S        Nigel Douglas,

SAURON      Tim de Zeeuw,

S-CAM       Michael Perryman,

Ultracam    Vik Dhillon,
[Ultracam not available at ING in Semester 2005A]

Applicants wishing to submit proposals to use a new (to ING) visitor 
instrument should read the following instructions:

Isaac Newton Telescope

Only one instrument/detector configuration is available on the INT:

Instrument        Detector
WFC               4xEEV

The WFC is offered in the default rotator position angle of 180-degrees 
only. However, in exceptional circumstances other rotator angles can be offered 
for the duration of the run only, i.e. changes to rotator angle during a 
run are not permitted.

ING, in collaboration with Prof. John Beckman of the IAC, has recently 
purchased two H-beta filters for the WFC on the INT, H-beta broad (4861/170) 
and H-beta narrow (4861/30). These filters are offered in semester 2005A.

INT observing time is allocated in blocks of one week on average, and 
observing programmes shorter than *4* nights are not accepted, unless 
explicitly agreed in advance by the Head of Astronomy or the Director 
of ING.

For the UK community, the PATT2 application form allows a 2-page scientific 
justification for INT proposals which are either long term (multi-semester) 
or are coordinated with other telescopes.

2. OASIS Offered on a Shared-Risks Basis

The optical integral-field spectrograph OASIS, formerly at the CFHT, had 
successful commissioning runs on-sky with NAOMI in 2003, and further 
commissioning is scheduled in semester 2004B. OASIS is offered to the 
community on a shared-risks basis in semester 2005A.

OASIS is now mounted permanently with the adaptive-optics system NAOMI, 
in the WHT's new AO-dedicated Nasmyth enclosure GRACE. Prospective 
applicants are reminded that the best-seeing period at ING occurs in the 
summer months (summer median seeing 0.5-arcsec, winter median seeing 
0.8-arcsec), but applications are  welcome for all parts of the semester. 
Observations with NAOMI/OASIS will be carried out by ING staff in queue 
mode, and are on a shared-risks basis.

PIs need not budget for overheads such as spectral calibrations; standard 
calibration observations will be made routinely by ING staff as an 
integral part of the queue observations.

For further information on OASIS please refer to the web page:

3. INGRID Not Offered at Cassegrain Focus

INGRID is not offered at the Cassegrain focus in 2005A, but is offered 
at the GRACE Nasmyth focus with the adaptive optics suite. Applicants 
are reminded that INGRID can also be used in GRACE with the AO loop 
switched off; in this case a guide star is not needed, and throughput 
is reduced by ~0.5 magnitudes compared to that at Cassegrain. The FoV 
of INGRID in GRACE is 42 arcsec.

At the Cassegrain focus, infrared imaging observations may be carried 
out with LIRIS (Section 4). The FoV of LIRIS at the Cassegrain focus 
is 4.2 arcmin.

4. LIRIS Offered on a Shared-Risks Basis

The long-slit intermediate resolution infrared spectrograph, LIRIS, 
built at the IAC, has imaging, long-slit and multi-object spectroscopy 
modes in the near-infrared (0.9-2.4 microns), and uses a Hawaii 1024x1024 
HgCdTe detector operating at 65K. It is mounted at the Cassegrain focus; 
the plate scale is 0.25 arcsec/pixel and the field-of-view is 4.2 arcmin.

LIRIS had a successful commissioning runs in 2003A and 2004A, and further 
commissioning is scheduled in 2004B. It is therefore offered in both 
imaging and long-slit spectroscopy modes in 2005A on a shared risks 
basis. LIRIS in multi-slit mode is available only in collaboration with 
the instrument builders; prospective applicants for LIRIS in this mode 
should contact Dr Arturo Manchado ( in the first instance.

For further information on LIRIS and its performance please refer to 
the ING and IAC LIRIS web pages:

5. WYFFOS Long-Camera Offered on a Shared-Risks Basis

The WYFFOS long-camera was commissioned at the end of July. However, 
due to adverse weather and technical problems unrelated to the long-camera, 
it did not prove possible to fully characterise its efficiency or 
throughput of the fibres. We expect an improved performance compared to 
the short-camera, but new performance figures will be published in 
October following the next AF2 service nights. Therefore the long-camera 
is offered with the 2xEEV mosaic for AF2 and the visitor instrument 
INTEGRAL in 2005A on a shared-risks basis.

Further information on the performance of the long-camera will 
appear on the AF2 web pages as it becomes available:

6. Backup Proposals for Adaptive Optics

In order to provide backup for periods of unsuitable atmospheric 
conditions for NAOMI and OASIS observations, we encourage proposals 
for ISIS which can be carried out in any sky conditions (that is, 
unspecified seeing and sky brightness).

Such proposals will be reviewed by the national TACs in the usual way, 
and we envisage at least one such proposal per TAC will act as backup 
to the NAOMI/INGRID and NAOMI/OASIS service-mode periods.

7. Opticon Trans-national Programme

Access to the ING telescopes under the auspices of the EC-funded 
Research Infrastructure Programme OPTICON is available to eligible 
astronomers from EU Member States and Associated States, and EC funding 
is available to cover their travel, accommodation and subsistence 
costs. Applications from new users and young researchers, and astronomers 
from countries without similar research facilities, are strongly 

Proposals can be submitted to any of the ING time allocation committees 
by following their submission procedures and deadlines (Section 11), and 
will be judged strictly on scientific merit. Applicants are urged to 
read the local Opticon web pages for detailed information on eligibility 
and other aspects of the programme

8. Time-share Agreement with TNG for NL and UK Observers

The time-share agreement with the TNG has proved to be very successful 
in previous semesters, and continues in semester 2005A. In this scheme, 
NL and UK observers may apply to use three TNG instruments. These are:

 + The high resolution spectrograph, SARG
 + The near infrared camera-spectrometer, NICS, in non-AO
   spectroscopy mode only
 + The multi-object low-resolution optical spectrograph, DOLORES

A minimum of five nights is available in total on the TNG in semester 
2005A to the NL and UK communities, and in return the Italian 
community obtains access to the WHT for the same number of nights.

For further details on the TNG observing guidelines and for instrumentation 
details, refer to:

Please note that NL and UK applicants for SARG, NICS or DOLORES should 
apply using their standard PATT form and should send these to their own 
national TAGs, and not directly to TNG. (CAT observers should apply for 
TNG time in the usual way). Successful applicants who meet the Opticon 
criteria of eligibility will be entitled to apply to the Opticon 
Trans-national Access Programme for their travel, accommodation and 
subsistence costs.

NL- and UK-based astronomers may not apply to use the WHT via the 
timeshare agreement, but instead should submit their WHT applications 
directly to their own national TAC.

9. Telescope Support: INT Support Model

Applicants are reminded that due to the impact of cost savings at ING, 
and operation of the INT as a single-instrument telescope, Telescope 
Operator (TO) support is no longer provided on the INT.

TO support continues to be provided for each night of all WHT runs, 
and astronomical support is provided on the first night of each run 
on the WHT and, by student support astronomers, on the INT.

Observers are reminded that filter and/or grating changes within a 
run will be accommodated provided that they have been explicitly 
requested in the telescope proposal. However, due to limited human 
resources, additional changes to the instrumental configuration may 
not be accommodated.

10. New Visitor Instruments on the WHT

PIs considering a proposal to the WHT around a new visitor instrument 
(i.e. new to ING) should email the Director well in advance of the 
proposal deadlines stating their intent, and should also submit a 
Technical Appraisal form. Further information on the protocol to be 
followed for submitting proposals centred around new visitor instruments, 
and a link to the Technical Appraisal form, is available at:

11. Proposal Submission Details

Details of how to submit a proposal, including deadlines, are given 
on the web pages of the Dutch, Spanish and UK time allocation
