Estimated Total Execution Time (hours, including overheads)

• 2

General Description

• Lineaer and circular spectropolarimetry of the Moon. OB execution will
   be a bit tricky.

Waiver Requests

• Waiver request to excced 1h observation time and to read with 4 port and
   low gain in spectropolarimetric mode

Critical Observing Condition Constraints

• Moon observations must be performed according to the instructions below

Time-Critical Aspects

• Execute it on night 2006-12-14/15 +/1. Preferably, BRIGHT OB should be
   executed on 2006-12-13/14. DARK OB should be executed on 2006-12-14/15

Special Execution Requirements

• - Load OB Moon Last Quarter DARK or BRIGHT in BOB (see time critical aspects
   for details).
  
  - In the acquisition template:
  1) Enter coordinates RA and DEC corresponding to t0 + 5 minutes, where
  t0 is the UT NOW
  2) Enter additional velocity corresponding to t0 + 10 minutes. Note that ephemeris
   give arsec/hour, whereas you have to enter arcsec/sesc (i.e., divide the value by
   3600)
  3) Change readout mode to ABCD,1x1,low
  
  - In the throughslit template:
  2) Change readout mode to ABCD,1x1,low
  
  - The TIO WILL UPDATE the additional tracking velocity every 5 minutes or so
  
  - Execute the OB:
  1) Once the first acquisition image arrives: do not panic, you will see nothing,
   or maybe something at the edge of the field.
  2) The TIO sends an offset to the WEST or EAST equal to half of the diameter value
   given in the Ephemeris files at time NOW
  For the last quarter, offest will be WEST to see the DARK side, will be EAST to
   see the BRIGHT side
  3) When telescope is in position, click on the RTD to send a very small offset,
   set exposure time to 1s, and repeat.
  4) Once the acquisition image has arrived, set "cursor" mode and click on the lower
   part of the Moon limb
  5) Repeat the acquisition image
  6) Click on QUIT
  7) Perform the through slit
  8) Leave the science templates to go
  
  - When OB has finished, set preset FALSE in the acquistion template, and get another
   acquisition image.
  
  A good time to start is when moon is at airmass approximately equal to 2.5

Special Calibration Information

• Use the user provided OBs in run C. They need not be exectued on the same
   night as run B observations

ToO Information

• This is not a ToO

ToO Activators List

• ---(Empty)---

Is this a Pre-imaging run ?

• false

Pre-imaging Requirements

• no pre-imaging is needed to point to the Moon; in fact, we have not even
   provided finding charts

Source(s) of Pre-imaging

• ---(Empty)---

Pre-imaging sources not listed above

• ---(Empty)---

Do all your OBs comply with the instrument-specific requirements listed
 on the instrument-specific Phase 2 web page ?

• YES

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 ?

• N/A

If you submitted OBs for standard stars, did you specify the magnitude
 and spectral type of all standard stars in the OBs ?

• YES

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

• YES

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

• YES

If you have preferences which OBs should be executed first, did you make
 use of the User Priority field in the OBs ?

• N/A

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

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 ?

• N/A
