Abstract:
Examples of NICMOS ATTACHED PARALLELS, including suggested MULTIACCUM
sequences.
Questions
Observing_Description:
As described in the NICMOS Handbook (pp. 27-28) and in the Phase 2
Update, proposers are asked to add attached parallels to their NICMOS
primary observations, whenever this does not affect the primary
science.
Attached parallels are defined as observations in the two NICMOS cameras
which are not used for the primary science.
Some proposers may have already requested the use of all three Cameras
for their science, but some other may have not (e.g., it is not needed
for their science). Those who didn't, should follow the guidelines
given in the Handbook and the Phase 2 Update. It should be kept in
mind that there is the potential for the three NICMOS Cameras to come
back to parfocality once in orbit.
Since attached parallels will be most useful when long integration times
are available, the recommendation is to add attached parallels whenever
the exposure times in the prime Camera are LONGER than 10 minutes at EACH
fixed telescope pointing.
Below two examples are given (one for each visit) of attached parallels:
one for broad band filters, to be applied to extragalactic observations,
to Galactic Plane observations, and to Molecular Cloud observations
when more than 4 orbits are available (see the Handbook); the other
for narrow band filters, which should be implemented when observations of
Molecular clouds require less than 4 orbits.
For illustrative purposes, in the first example, NIC2 is the primary
Camera; in the second example NIC1 is primary.
The suggested readout mode is MULTIACCUM, with the sequence SPARSE256, in
all cases.
N.B.: In general, users should define a Generic Target (see below) for the
NICMOS attached parallels. In this way, they will not need to specify a value
of the ORIENT for the pointings of the parallel detectors. The same Generic
Target can be used for all exposures and all visits in the proposal. The
specification of the Generic Target is not needed when the primary observation
already requires an ORIENT.
Proposers are encouraged to process through RPS2 their primary proposal,
BEFORE adding the attached parallels, to ensure that the efficiency of the
observations is not affected by the subsequent addition of attached parallels.
