General Description

This is a MOS-spectroscopy run with one image of 60 seconds, then with
 3 images of 27 minutes at 3 offsets for the spectroscopy, and finally 1 image for
 night arc. This is done for all the 16 OBs and with all the same instrument setup
 (the first image is with the R filter and then the 3 images of spectroscopy are
 done with the GG475 filter with the HR_red grism).

The goal is to perform the MOS-spectropscopy. All the science OBs first point telescope
 to coordinates with suitable guide stars and then perform 1 exposure of 60 seconds
 and then 3 images of 27 minutes with 3 offsets and the the arc exposure.

The total science exposure is 21.6 hours and the execution of all our OBs, based
 on P2PP, will take 29 hours and 10 minutes (which is the time we asked for). However,
 more time was needed for the pre-imaging run, so we are aware that less time will
 be given for our MOS-spectroscopy run. Please, follow-up our priority list in "Special
 Execution Requirements". 

There is no OBs for calibration since it is not mandatory in PRE-IMAGING mode. (Calibration
 will be given with our data.)

Waiver Requests

A Waiver Request was submitted and approved by Marina Rejkuba (mrejkuba@eso.org)
 : the OBs least 1h 50min (more than 1hour).

Critical Observing Condition Constraints

Observations needs to be done within +/- 2 hours from the meridian. Therefore,
 observations need to be done bellow and airmass of 1.20-1.25 for our targets (all
 our targets have declination from -50.6 to -54.4 degree).

The only other constraints are to have a seeing less then 1.2 arcsec, lunar illumination
 of less then 0.5 and Moon angular distance of 30 degree or more. We also need a
 clear sky (as asked in our Phase 1 proposal).

Time-Critical Aspects

There is no Time-Critical Aspects. However, as point out in "Critical
 Observing Condition Constraints", observations needs to be done within +/- 2 hours
 from the meridian.

Special Execution Requirements

Because time needed for the pre-imaging run was higher than time allocated,
 we are aware that less time will be given for our MOS-spectroscopy run. Please,
 follow this priority list 

PRIORITY 1 (SHOULD ALL BE DONE BECAUSE IT NEED ONLY HALF OF ESTIMATED TOTAL EXECUTION
 TIME) 
MOS_IC2391_031
MOS_IC2391_034
MOS_IC2391_101
MOS_IC2391_104
MOS_IC2391_201
MOS_IC2391_204
MOS_IC2391_241
MOS_IC2391_244

PRIORITY 2 (DO AS MUCH AS YOU CAN, STARTING FROM THE FIRST OB LISTED HERE TO THE
 LAST ONE)
MOS_IC2391_032
MOS_IC2391_033
MOS_IC2391_102
MOS_IC2391_103
MOS_IC2391_242
MOS_IC2391_243
MOS_IC2391_203
MOS_IC2391_202

Also, as point out in "Critical Observing Condition Constraints", observations needs
 to be done within +/- 2 hours from the meridian.

Special Calibration Information

There is no OBs for calibration since it is not mandatory in MOS-spectroscopy
 mode. The calibration frames (bias, sky flats, and spectrophotometric standard star
 observation) will be delivered to us together with the MOS-spectroscopy data when
 the MOS-spectroscopy run will be completed. Arc observation are done in each OBs.

Pre-imaging Requirements

```
Pre-imaging is already done.

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 ?

```
N/A
```

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 ?

```
N/A
```

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

```
N/A
```

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

```
N/A
```

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 ?

```
N/A
```

Did you specify suitable guide stars for all your OBs using Guidecam ?

Did you check that the chosen guide stars are suitable for all the offset positions and that they do not produce unacceptable vignetting of the field of view ?
