2. Opportunities/Questionnaire for Narrow Band Imaging with the INT


The International Scientific Committee (CCI) of the Roque de los Muchachos
(ORM) and Teide (OT) observatories invites applications for International Time 
Programmes (ITP) on telescopes installed at these Observatories. The ITP offers 
up to 5% of the observing time, evenly spread throughout the year and the lunar 
cycle, at the telescopes listed below. An ITP proposal can request observing time 
over a period of up to two subsequent years. Full details of the scheme for night-time 
telescopes can be found at

Proposals are considered on an annual cycle and the closing date for submission 
of proposals to the 2004 ITP is Friday 6th February, for projects which may start 
during the fall of the same year.

Proposers must bear in mind that specific instrumentation may not be available 
at all times and that the CCI does not schedule the observing time as this is 
done by the corresponding technical committees of each telescope or group of telescopes.

The aim of the ITP is to encourage large-scale international scientific projects 
of the highest quality, which cannot easily be accommodated within other time 
allocation schemes.  Proposals should be international in their range of participants 
and are expected to involve astronomers from at least two of the European countries 
that have signed the Agreements for Cooperation in Astrophysics.  They can 
include astronomers from scientific institutions in any of the countries 
associated with the EC's Framework Programmes and may entitle them to reimbursement 
of travel and accommodation costs related to their participation in the observing 
programme.  Moreover, such proposals can include astronomers from scientific 
institutions from any other country in the world, but this does not entail the 
right to reimbursement of their expenses.

The observing programmes should concentrate on a single large-scale astronomical 
investigation.  Proposals that would benefit from the use of more than one facility, 
and which would be unlikely to obtain the necessary observing time through the usual 
time allocation panels because of the scale of the project, or because of the 
difficulty to coordinate several telescopes, are especially encouraged.  However, 
collaborative international projects that require the use of a single facility 
are also welcome.

Scientific excellence is a prime consideration.  Each proposal will be assessed 
scientifically by the CCI, which reserves the right not to make an award on one or 
more telescopes if the quality of the proposals is not adequate to justify their use.

The CCI may award time to one or more projects.  Once a project is selected, and 
with the agreement of the Instituto de Astrofísica de Canarias, any Spanish 
institution shall have the right to join the programme if it wishes.

Annual brief progress reports will be required by the CCI from successful applicants.  
On completion of the programme, and not later than two years after the final period 
of observing time, a full report should be submitted to the CCI for publication in 
its Annual Report.


      Opportunities/Questionnaire for Narrow Band Imaging on the INT

As of semester 2003B the INT is being operated as a single instrument
telescope, the instrument being the Wide Field Camera (WFC).   The 
community is reminded that the available filters for the WFC comprise a good 
range of narrow band filters suitable for exploitation of bright time.  The current 
list includes the following ING owned filters (filter  central_wavelength/bandpass);

OII    3737/100
HeII   4686/100
OIII   5008/100
Halpha 6568/95
SII    6725/80

plus the following privately owned filters which are also available to the 
ING community (filter  central_wavelength/bandpass owner/email);

Halpha redshifted 9190/50   Alfonso Aragon Salamanca 
Halpha redshifted 8160/50   Alfonso Aragon Salamanca
OIII redshifted 5027/60     Nial Tanvir

For these privately owned filters prospective applicants should first contact 
the appropriate owner.

In addition the ING is seeking to expand the choice of available filters and is 
actively pursuing the purchase of the following filters in 
collaboration with John Beckman at the IAC;

Hbeta broad  4861/170
Hbeta narrow 4861/30

As part of this on-going process we are anxious to hear from individuals 
who have a need for filters not listed above.  Please send any suggestions for 
additional filters to 

 Romano Corradi (INT Telescope Manager)  Robert Greimel 
(WFC Instrument Specialist)

Suggestions may be sent at any time but should include a brief statement of 
scientific interest plus a short technical description of the 
filters required (minimally central_wavelength and bandpass).
