Estimated Total Execution Time (hours, including overheads)
General Description
This is a proposal for imaging 1 galaxy using 2 filters: 1 feature + 1
continuum.
NGC5743 will be observed with filters: B11.7 (11.3um PAH) and NeII_1 (PAH continuum).
Each OB contains the observation of a feature-continuum pair and is divided in 8
subsets:
feat. -> cont. -> feat. -> cont -> ... of 340s of on-source integration
time each. The total integration time for each OB is 1h 29m (including acquisitions
and overheads; a waiver has been approved). All OBs sum a total integration time
of ~3h.
2 finding charts are attached:
(1) A 2MASS K-band image of the galaxy covering the central 4 arcmin. A red square
(showing approx. the
VISIR FOV) marks the location of the target.
(2) A 2MASS K-band image of the galaxy covering the central 1 arcmin. The red square
is as in (1) and the red cross marks the center of the galaxy. This is the position
that should be placed in the center of the top-left quadrant of the detector. This
is important to keep the whole galaxy
emission within one quadrant and to not contaminate the others.
The acquisition template used for acquiring the target is "VISIR_img_acq_Prset",
as the target is faint and diffuse, so it will not be easily visible in acquisition
images. Science observations are "VISIR_img_obs_AutoChopNod", SEQ.CHOPNOD.DIR =
PERPENDICULAR and TEL.CHOP.POSANG = TEL.ROT.OFFANGLE = 45 (as in the acquisition
template). A random jitter of 1 arcsec has been set.
The (preferably "Cohen") photometric standard star provided by the observatory
should be observed close
in time (before/after) to the target so that it matches its airmass. Besides it
should be observed with all the filters defined in the OBs that have been executed.
Thank you very much in advance!
Waiver Requests
Critical Observing Condition Constraints
As requested in the proposal, the observing conditions should be _photometric_
and the seeing always lower than 0.6", which implies diffraction limited observations
(0.35") at ~10um. The airmass should be also lower than 1.3.

Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
If the provided finding chart is at a different wavelength than the observations,
did you clearly describe in the README file how to identify the target?
Did you specify a guide star brighter than V=12mag within a field of
r=5arcmin around the science target?
