Abstract for MTS:
FORS1 IPOL program of moving targets with R bessel filter. For each target, the OBs (imaging linear polarization) should be executed at different phase angles, as specified in Section "Time-critical aspects". Each OB consists of acquisition plus 8 or 16 exposures with the lambda/2 retarder waveplate at 0, 22.5, ... deg. Several OBS have a execution time >> 1h. OB execution cannot be splitted. Target coordinates, as well as additional velocity, must be entered according to the ephemeris files (see Section "Time-Critical aspects"). Waiver request: 178.C-0036I.01: OB execution longer than 1h. No finding charts submitted (moving target). Time-Critical Aspects ===================== Each OB should be executed in the time intervals specified below. These intervals have been selected according these criteria: 1) to satisfy the observing constraints (visibility and and lunar illumination); 2) to cover adequate target phase coverage 3) to avoid background crowdness (i.e., we have avoided those observing when our targets are too close to brighter objects). TIME CONSTRAINTS ARE WELL SPECIFIED IN THE OB NAMES (and refer to UT!!!) We are aware that time constraints will be respected on a best efford basis. OB ID 317406 From July 1 UT 00:00 to August 01 UT 00 317445 From September 5 UT 00:00 to September 14 UT 00:00 317448 From April 1 UT 00:00 to April 11 UT 00:00 317449 From April 30 UT 00:00 to May 8 UT 00:00 317450 From May 29 UT 00:00 to June 7 UT 00:00 317455 From April 29 UT 00:00 to May 11 UT 00:00 317456 From June 1 UT 00:00 to June 8 UT 00:00 Special Execution Requirements ============================== Target coordinates and additional tracking velocity must be typed in prior OB execution based on the ephemeris provided as function of UT with the OB. OB execution cannot be splitted in two or more parts. Please have a look at the photon counts and check carefully for saturation (the magnitude of our targets may be slightly different than expected)
