1. ING Instrumentation in Semester 2005B

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
INGRID             1kx1k HgCdTe   At Nasmyth only, 42 arcsec FoV 
NAOMI/INGRID       1kx1k HgCdTe
OASIS              2kx4k MIT/LL
NAOMI/OASIS        2kx4k MIT/LL
LIRIS              1kx1k HgCdTe

Adaptive Optics
All AO observations are carried out in service 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,
PN.S        Nigel Douglas,
SAURON      Tim de Zeeuw,
S-CAM       Michael Perryman,
Ultracam    Vik Dhillon,

NB: INTEGRAL is available with the WYFFOS long-camera only.

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, when there is compelling scientific 
justification, other rotator angles (0, 90 or 270-degrees) can be 
offered for the duration of the run only; changes to rotator 
angle during a run are not permitted. Such requests should be
justified in the original telescope proposal.

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.


The optical integral-field spectrograph OASIS, formerly at the 
CFHT, had successful commissioning runs on-sky with NAOMI in 
2004, and further commissioning is scheduled in semester 2005A.

OASIS is mounted permanently with the adaptive-optics system 
NAOMI, in the WHT's new AO-dedicated Nasmyth enclosure GRACE;
It can be used with or without adaptive optics. Prospective 
applicants are reminded that the best-seeing period at ING 
occurs in the summer months, but applications are  welcome 
for all parts of the semester. Observations with OASIS or 
NAOMI/OASIS will be carried out by ING staff in service mode.

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 service 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 2005B, 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.


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 has been successfully commissioned, and is offered in both 
imaging and long-slit spectroscopy modes in 2005B. 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:


The WYFFOS long-camera was commissioned successfully in August 2004. 
Due to adverse weather it has not proved possible to fully
characterise its efficiency and throughput of the fibres; the latest 
performance figures are listed at:

The long-camera is offered with the 2xEEV mosaic detector for both
AF2 and the visitor instrument INTEGRAL in 2005B.

6. ULTRACAM Expected To Be Offered in 2005B

ULTRACAM is expected to be offered on the WHT in 2005B. Prospective
applicants should contact Dr Vik Dhillon (
in the first instance for further details. Information on the 
performance and capabilities of ULTRACAM are available at:

7. 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.

8. 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 encouraged.

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

9. 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 
2005B. In this scheme, NL- and UK-based observers may apply 
to use three TNG instruments. These are:

  + The high resolution spectrograph, SARG
  + The near IR 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 2005B 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 to the timeshare 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.

10. 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.

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.

11. 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:

12. 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 panels:
