Estimated Total Execution Time (hours, including overheads)
General Description
The purpose of this run is obtaining high precision photometry of the
young open cluster Pismis 11. The cluster has to be observed through the standard
UBVRI filters. There are short, intermediate and long exposures defined, so that
the whole range of magnitudes is covered.
Ideally, we would like all the observations to be carried out during the same night
with a standard field observed at several different airmasses. However, we understand
that this cannot be guaranteed with service observations. We provide 8 OBs for extra
observations of standards. This is a single Landolt field that we would like to
have observed whenever our objects are observed.
Waiver Requests
Critical Observing Condition Constraints
There are only two fields. The main part of the target and a small grouping
of stars to the North of the cluster (two OBs starting Northcluster). These two
OBs have lower priority than the rest. Ideally, we would like all the OBs called
Pismis11 executed during the same night with frequent observations of the standard
field SA101. The reason for this is that, in order to obtain high precision photometry,
very good treatment of the extinction is needed. In ideal circumstances, we would
have the 3 hours on target done in a single night and 4-5 observations of SA110
covering airmasses from ~2 to ~1.1. The OBs called Northcluster could be done during
another night with the remaining SA101 OBs.
If this is not possible, we would like to have ALWAYS at least one SA101 observation
each night
Time-Critical Aspects
Special Execution Requirements
Ideally, all OBs with name Pismis 11 done in one night and 4-5 observations
of SA110 at different airmasses. At least, try to make them in as few nights as
possible.
In the worse case scenario, we'd have one science OB observed in each different
night. If this is the case, please attach one SA110 OB to each science OB.
If several science OBs are done in one night, please at least bracket them within
two SA110 OBs. If more than 2 science OBs are done in one night, please take no
less than two SA110 observations covering a range of airmasses.
Special Calibration Information
Eight OBs of SA110 are provided as extra calibration. This is not so much
for the number of Landolt standards as for the need to trace the extinction well.
Please try to cover as much as possible in airmass with the SA110 OBs - fundamentally
the range in airmass covered by the science OBs. If you use up all the SA110 OBs
with the Pismis11 OBs, then take only standard calibration with the NorthCluster
OBs.

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 ?
