1. ING Instrumentation in Semester 2002B 

General Information

Detailed information on ING instrumentation offered for the forthcoming
semester can be found in the ING web pages at

and guidelines for proposal submission can be found at

Applicants should refer to these pages for the latest information.
Occasionally highly rated proposals may not be awarded time due to 
scheduling constraints.

Due to construction of the Adaptive Optics Nasmyth platform (GRACE), 
UES and INTEGRAL will not be available in this semester. In the
meantime, access to high-resolution spectroscopic instrumentation has
been secured through a time-share agreement with the Italian National 
Telescope Galileo (TNG) on La Palma. For details see the following
section of this INGNEWS issue.

Instrumentation Overview


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 proposals for six or
more nights. 

The following instrument/detector configurations are available:

                Instrument      Detector 

                ISIS BLUE       EEV12 
                ISIS RED        TEK4 
                AUX-port        TEK1  
                PRIME           2xEEV Mosaic 
                AUTOFIB2/WYFFOS TEK6
                INGRID          1kx1k HgCdTe 
                NAOMI/INGRID    1kx1k HgCdTe  (shared-risks basis) 

NAOMI/INGRID: Observations will be carried out in service mode.
AUTOFIB2:     The large fibres module has been withdrawn. 

WHT visitor instrument contacts are:

PN.S     Nigel Douglas,
SAURON   Tim de Zeeuw,
S-CAM    Michael Perryman,
Ultracam Vik Dhillon,


The following instrument/detector configurations are available:

                Instrument      Detector 

                WFC             4xEEV 
                IDS 235/500     EEV10 or TEK5 

INT visitor instrument contacts are:

CIRSI   Richard McMahon,

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


Only one instrument/detector configuration is available:

                Instrument      Detector

                Direct imaging  2kx2k SITe2

The JKT only supports one common-user instrument, and private
are not accepted. Although there is no formal limit on the duration of 
observing runs on the JKT, short proposals are not encouraged, and 
observing time is usually allocated in blocks of ~1 week.

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

As part of a collaboration between ING and TNG, 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 in semester 2002B 
to the NL and UK communities, and in return the Italian community 
obtains access to the WHT for the same number of nights. More than 
five nights may be shared if such demand is balanced between both 

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

Select "instruments" for detailed information on SARG, NICS and

SARG is a high efficiency echelle spectrograph designed for the spectral
range from 370 up to 900 nm, and for resolutions from R=29,000 up to
R=164,000. Both single object and long slit (up to 30 arcsec) observing
modes are possible. A dioptric camera images the cross-dispersed spectra
onto a mosaic of two 2048X4096 CCDs.

NICS is the TNG infrared (0.9-2.5 Ám) imaging spectrometer, utilising
a HgCdTe Hawaii 1024x1024 array. Its observing capabilities include
imaging (4.2'x4.2' FoV), high-throughput low resolution spectroscopy 
(RS=50-500), medium resolution spectroscopy (max-R=2500), imaging
polarimetry, spectropolarimetry and, when coupled to the adaptive optics
module, near diffraction limited imaging. It is offered to NL and UK
applicants in non-AO spectroscopic mode only.

DOLORES (Device Optimized for the LOw RESolution) is a focal reducer 
instrument installed at the Nasmyth B focus of the TNG. The detector is 
a Loral thinned and back-illuminated 2048x2048 CCD. The scale is 0.275
arcsec per pixel, which yields a field of view of about 9.4 x 9.4
The instrument allows imaging through broad and narrow band filters as
well as spectroscopic observations with resolving powers between RS=300 
and RS=3000. 

Please note that NL and UK applicants for SARG, NICS or DOLORES should 
apply using their standard PATT/NL form and should send these to their 
own national TAGs. DO NOT APPLY DIRECTLY TO TNG.  (CAT observers should 
apply for TNG time in the usual way). Successful NL and UK applicants
TNG will qualify for EC funding under the auspices of the EC's Access to
Research Infrastructures Programme to cover travel, accommodation and 
subsistence costs, assuming they meet the criteria for eligibility. For 
further details of this general scheme see:

3. The ING Service Programme

Prospective applicants to the JKT Service Programme are reminded
that due to the impact of cost savings at ING, the scheme of service 
observing carried out by observatory personnel will be discontinued 
on the JKT from the end of Semester 2002A. The INT and WHT Service
Programmes will continue in their present format until the end of
Semester 2003A, when the INT Service Programme will also be

4. Definition of Dark, Grey and Bright Time

Beginning with Semester 2002B, the definition of dark, grey and bright
categories used in creating the telescope schedules will change. The 
historical method, based upon the fraction of each night that is
does not give a consistent mapping in terms of sky brightness. The
to be adopted is based on the fractional illumination of the Moon, k: 

 Dark:   0.00 .le. k .lt. 0.25
 Grey:   0.25 .le. k .lt. 0.65
 Bright: 0.65 .le. k .le. 1.00

The ING exposure time calculator,SIGNAL, has been modified to offer an 
option specifying 'typical' sky brightnesses for dark, grey and bright 
time, corresponding to V=21.5, 19.75 and 18.50 magnitudes/arcsec^2 
respectively. Proposals for darker conditions must of course be

A short article explaining the reasons for this change will appear in 
the forthcoming edition of the ING Newsletter, and a longer article is 
available as ING Technical Note 127:

5. Telescope Support

Astronomical support is provided on the first night of each run
on the WHT, INT and JKT. Telescope Operator (TO) support is provided 
for each night of all WHT runs. INT Wide Field Camera runs have TO 
support for the first two nights only, and INT IDS runs of six or more 
nights will have TO support for the first four nights only. TO support
is not provided on the JKT. 

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
