Estimated Total Execution Time (hours, including overheads)

• 23 hrs

General Description

• This is a program aimed at investigating the escaping fraction of ionizing
   radiation from galaxies at z ~3 in GOODS-South.
  
  The 23 submitted OBs are essentially 2 masks, with mostly the same targets but rotated
   180 deg each other: mask MOS_GOODS_1 OBs are 12 times the same OB (1 hr long). mask
   MOS_GOODS_2 OBs are 11 the same OB (1 hr long). The OBs can be executed in any order.
  
  We selected 7 reference stars for the first mask and 9 reference stars for the second
   mask which should give a good S/N for centering in the 45 seconds of acquisition
   step (the ETC has been used with 1".0 seeing). We didn't use any preimaging: the
   previous very succesfull runs of GOODS-FORS2 have shown that mask design using ACS
   mosaic results in  very reliable masks.
  
  SLIT CENTERING!
  Mask 1 (MOS_GOODS_1)
  4 slits (#19, #15, #4, #1) have been placed on point like objects and should be
   centered in their slits after the through slit step. The sources which are the targets
   of these observations are relatively faint and thus could not  be visible in their
   slits after the through slit step.
  
  Mask 2 (MOS_GOODS_2)
  3 slits (#1,#5, #19) contain point like objects which are expected to be centered
   in their slits after the through slit step.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Dark time is mandatory since the most important part of the spectra to
   be analized is ~<4000 Angstrom

Time-Critical Aspects

• No time critical aspects

Special Execution Requirements

• No special execution requirements

Special Calibration Information

• No special calibration information required

Is this a Pre-imaging run ?

• false

Pre-imaging Requirements

• No preimaging required: GOODS-South is supposed to be one of the best
   astrometrized fields.
