Estimated Total Execution Time (hours, including overheads)

• 19:59

General Description

• For each target (science and standard stars), we will obtain an acquisition
   image, in order to center the object on the 1046,1076 pixel.
  Then we will image in polarimetric mode, at four different Wollaston prism angles,
   3 to 5 individual integrations.
  We propose to reobserve three targets (LHS_102B, 2MASS_J0036+18 and 2MASS_J2244+20),
   with a flexible time delay (but not in the same night). The second observation has
   a lower priority.
  Some targets may have a nearby object. As long as both objects appear in the IPOL
   strip, we'll be able to get polarimetric measurements, so identifying which is which
   is not crucial.
  All observations use the I_BESS filter, except for targets 2MASS_J1207-39, GY_5
   and UScoCTIO_112, for which we alse ask for a R_BESS measurement (with lower priority).
   The optimal time delay would be within the same night, but any delay is acceptable.

Waiver Requests

• Waiver for 1h19min OBs granted with the restriction that if the conditions
   
  degrade in violation of the constraints after the first hour, the OB 
  will not be repeated.

Critical Observing Condition Constraints

• All targets can be observed with thin cirruses, with seeing up to 1.4"
   (some seeing incursions to larger values are acceptable), as stated in the OBs and
   in the proposal. Some isolated bright targets can be observed with a higher seeing
   (up to ~1.6").
  Exposure times have been calculated for a seeing a 1". A better seeing would result
   in saturation problems (relatively long exposure times are required to obtain an
   SNR>~3000 while keeping overheads low).

Time-Critical Aspects

• We propose to observe three targets twice: LHS_102B, 2MASS_J0036+18 and
   2MASS_J2244+20. The second observations can take place at any time, but not in the
   same night as the first night.
  On the contrary, R_BESS observations could take place at any time after the I_BESS
   observations, and preferentially within the same night.

Special Execution Requirements

• None.

Special Calibration Information

• Each science target should be observed with one polarized standard star,
   as stated in the Calibration plan (polarized standard stars are as often as needed).
   I do not include OBs for these standard stars.

ToO Information

• No ToO.

Is this a Pre-imaging run ?

• false

Pre-imaging Requirements

• This is not a Pre-imaging run.
  During the acquisition:
    each target (science and standard stars) should be positioned on the 1046,1076
   pixel (using the acquisition image). 
    This is rather important.
