Major Instrument Modes: FORS1 IPOL

RA Range: 16:15

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.2 2CLR 2.0 0.7 60.


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? Yes! ToO? No! Carry-over run? No!


Special Remarks:
OB 122536 should be executed in any suitable night in July, preferably around mid July.


 
 
Imaging polarimetry of Kuiper-Belt Object 2001-KX-76. The object
is moving slowly, so only RA and DEC need to be updated according
to the included ephemeris table. 

Time constraints: OBs should be executed within 2-3 days from the day
given in their name (see also the Time Constraints sets in the OBs).
Moon constraints can be relaxed in order to match the time constraints,
which are fundamental for the observations to be scientifically
useful.

Acquisition: object identification is not needed and clicking on the
center pixel of the chip (approximately) is enough.

All OBs but three (115365, 115366 and 121741) can be executed at two
different epochs.

Even though many more than 4 retarder plate angles are used in the
science OBs, the IPOL standard can be taken only in the four ones of
the calibration plan.

Waiver approved for 2h 14 m OBs. OBs should not be interrupted,
but, rather, seeing constraints can be relaxed to 1.5" for up
to 30% of the integration.
