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.
Please refer to the information provided by every TAC regarding acceptance of proposals submitted by PIs employed or studying in a country other than TAC's.
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.
 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
Nights on which service time is available are flagged on the
by 'S' or 'S/D' in the 'Programme' column. Observations are made by ING staff.
 Typically ~ 4 - 5 months before the start of
 Specific nights are allocated each semester, flagged in the
ING schedules as
'CAT S' (service) or 'CAT DDT' (DDT-IAC).
CAT S observations are done by IAC support astronomers.
Applications for override observations should be submitted to the TACs
in the same way as proposals for scheduled time.
This definition of a target of opportunity can 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. Observations are made by the overridden observer.
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.
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.
