Estimated Total Execution Time (hours, including overheads)

• 19.6 hours (16 science + 3.6 special calib, see waiver requests)

General Description

• This is a standard VIMOS MOS run. Targets are ultra-compact dwarf galaxy
   candidates in the Hydra and
  Centaurus clusters. The run consists of 5 pointings (2 in Hydra, 3 in Centaurus)
   with one mask for each pointing, i.e. 5 different masks for each quadrant. Each
   pointing has 2 identical OBs (e.g. hyd_f1-0 and hyd_f1-1), i.e. a total of 10 science
   OBs (4 Hydra, 6 Centaurus), each one with night-time arc template included. Priorities
   are higher for *-0 OBs. OBs are longer than 1 hour, a waiver request had been granted.
  
  There will be 10 Lick-standard OBs for calibration.
  WE ASK THOSE TO BE TAKEN DURING TWILIGHT! 
  See 2nd waiver request and special calib information for more details.
  
  The Hydra pre-images arrived earlier, since Hydra has 2 hours lower RA. Therefore,
   Hydra OBs are submitted before the Centaurus OBs. 
  
  Submission of the 10 Lick standard OBs will be completed beginning of February.

Waiver Requests

• There were 2 approved waivers.
  
  1. 076.B-0293B.01.WAV: This was a waiver for > 1 hour OBs, which was approved.
   OBs finally will have 1:36 hr execution time.
  
  2. 076.B-0293B.02.WAV: We asked for and got granted 3.6 hours of additional twilight
   time to take 10 Lick standards. That is, total execution time of our program becomes
   19.6 hours: 16 hours science + 3.6 hours special calib. PLEASE TAKE THE LICK STANDARD
   OBs IN TWILIGHT!
  Reason for asking for additional time: originally we had asked for visitor mode
   and wanted to take standards in twilight. When granted service mode time, this effectively
   reduced a lot the time available for standards, which is why we asked for the exception
   to take Licks in twilight, in addition to the OPC approved execution time.

Critical Observing Condition Constraints

• none

Time-Critical Aspects

• none

Special Execution Requirements

• I have assigned different priorities to the OBs:
  
  For each field, the OB ending with "-0" has higher priority than that ending with
   "-1".
  That is: preference is spatial coverage, not depth.
  If RA pressure (e.g. from COSMOS) does not allow complete execution of our programme,
   it would be great if the first OB for each of the five fields is observed.

Special Calibration Information

• In total, 10 Lick standards shall be observed, see waiver requests.
  WE ASK THOSE TO BE TAKEN DURING TWILIGHT, PLEASE!
  
  
  The 10 Licks OBs will all have been submitted by beginning of February.
  
  Note that there are two Licks which form a double star system:
  HD 131976 and HD 131977. Finding charts have been attached to the corresponding
   two OBs.

 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
 ?

• N/A
