Applying for Telescope Time

Time on the 4.2-m WHT and 2.5-m INT is awarded primarily by the Dutch, Spanish and UK time-allocation committees (TACs), who meet once per semester. The A-semesters run from 1st February to 31st July, and the B-semesters from 1st August to 31st January.

Telescope proposals should be submitted directly to the TACs, following the instructions linked under 'Proposal submission information' in the table below, and by the deadlines given on the same pages.

The instrumentation available on the WHT and INT is summarised on the ING instrumentation overview page.

Notes:
[1] Applications are accepted from other countries, see below.
[2] The normal submission deadline for the ING service programme is the end of each month, and there are occasional announcements of opportunity, e.g. for time on visiting instruments. Nights on which service time is available are flagged on the ING schedules by 'S' or 'S/D' in the 'Programme' column.
[3] Typically ~ 4 - 5 months before the start of the semester.
[4] Specific nights are allocated each semester, flagged in the ING schedules as 'CAT S' (service) or 'CAT DDT'.

Principal Investigators (PIs) employed or studying in a Dutch, Spanish or UK institution at the time of submission should submit their proposal(s) to the Dutch, Spanish or UK TAC respectively. Proposals submitted to a national TAC by a PI employed or studying in one of the other partner countries may be assessed by that TAC or, at its discretion, may be passed on to the correct national TAC.

Each national TAC will also accept proposals from a PI based in countries other than the partner countries. Such international proposals (which must be in English) may be assessed by that TAC, or at its discretion may be passed to an international TAC comprising members of the three national TACs, and must be written in English.

Observing programmes of less than one night are not accepted on either the WHT or the INT unless agreed in advance by the Director of ING or the Head of Astronomy. For such programmes, please consider applying for service observations, see the relevant entries in the table above.

For both the WHT and INT applicants are encouraged to submit proposals for large time allocations. This applies particularly to the INT, where ING can only support a small number of instrument changes.

Applications for override observations should be submitted to the TACs in the same way as proposals for scheduled time. Applicants should first consult the ING overrides page and the proposal-submission advice provided by the individual TACs (linked above). This definition of a target of opportunity can also be useful when planning your submission. Note that override programmes for less-used instruments (e.g. WHT INGRID, OASIS or prime-focus imaging) are less likely to be schedulable than for the more popular instruments.

PIs planning to submit a proposal for observations with a visitor instrument which is new to ING should follow the procedure for new visitor instruments. This includes informing the Director of ING of the PI's intention, at least three months before the proposal deadlines.

The ING astronomy web pages provide additional relevant information, e.g. about: planning observations; observer support at the telescope; calculating exposure times; data ownership; and subscription to [INGNEWS] mailing list.

International Time Programme

Up to 5% of ING telescope time is available for large-scale international projects through the International Time Programme (ITP). This time is allocated on an annual basis by the International Scientific Committee (CCI). The proposal deadlines are usually in February, and the time is usually allocated over the following B and A semesters.

OPTICON time

The OPTICON scheme fosters pan-European access to the ING telescopes, under the auspices of the EC-funded Research Infrastructure Programme. OPTICON time is available to eligible astronomers based in EU member states and associated states, and EC funding may be available to cover travel, accommodation and subsistence costs. Applications from new users and young researchers, and astronomers based in countries without similar research facilities, are strongly encouraged. International proposals that otherwise meet OPTICON's criteria of eligibility, but which are submitted to and awarded telescope time by the national TACs, do not qualify for OPTICON financial support.
