Estimated Total Execution Time (hours, including overheads)
General Description
We want to observe 18 cluster in the Small Magellanic Cloud with FORS2/low-resolution-spectroscopy
facility. Our aim is to measure metallicities from the Ca tripplet. Spectroscopic
measurements of the iron content couppled with photometric-age
obtained from this PRE-IMAGING run, will allow us to obtain an accurate age-metallicity
relation for the galaxy. The parallel observations of field
stars will permit us a comparison of chemical evolution in clusters to the field.
This run (082.B-0505(A)) is a PRE-IMAGING observation. PhaseII OBs for spectroscopic
observations (082.B-0505(B)) will be prepared and submitted after the present run.
Waiver Requests
Critical Observing Condition Constraints
We had the observations approved with variable sky (thin cirrus),
seeing<=1.0, lunar illumination<=1.0, and the moon at least at 30 degrees
away from our targets.
For our observations airmass is not a critical parameters.
All out targets are close to the South Pole, so it is always lower than 1.5.
Time-Critical Aspects
Special Execution Requirements
In all our 18 PRE_IMAGING observations coordinates were choosen in order
to have the cluster centered on the FORS2-upper CCD (master).
For this reason in the attached finding charts, which cover exactly the FORS2 field
of view (6.8x6.8 arcmin), clusters are not located at the center of the chart itself,
but in the
upper part (about 1.5 arcmin north with respect to the chart-center itself).

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 you have prepared your finding charts with tools other than FIMS,
do they comply with the specifications on the FORS1 Phase 2 web page ?
