Estimated Total Execution Time (hours, including overheads)

• 06:02

General Description

• Polarimetric observations of two moving targets, i.e., two fragments of
   a comet. We request both IPOL in two narrow band filters, and PMOS with grism 300V,
   both circular and linear polarization, plus IMG in two narrow band filters. In addition
   to the science program, we request observations of a specphot standard star in IMG
   mode with the two narrow band filters.

Waiver Requests

• We have requested and obtained on 2006-06-01 authorization not to include
   finding charts (that would be of no use for moving targets). Waiver ID is 277.C-5018A.1

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• Observations should be executed as soon as possible as the comet is fading
   out.

Special Execution Requirements

• Since our targets are moving targets, coordinates and additional tracking
   velocity should be entered by the support astronomer as specified in the attached
   ephemeris. For IPOL observations, this will be sufficient. For PMOS observations,
   we ask the support astronomer to enter also the position angle specified in the
   ephemeris. Note that in the ephemeris the PA is positive North to South, whereas
   in the OB the position angle should be given with the opposit sign.
  
  Ideally, observations of circular polarization and linear polarization in the same
   mode and for the same fragment should be executed in the same night. E.g.:
  
  PMOS LIN and PMOS CIR for fragment B should be executed in the same night
  IPOL LIN and IPOL CIR for fragment B should be exectued in the same night 
  PMOS LIN and PMOS CIR for fragment C should be executed in the same night
  IPOL LIN and IPOL CIR for fragment C should be executed in the same night
  
  Finally, ideally, IMG for fragment B and IMG for fragment C and IMG standard star
   should be executed in the same night.

Special Calibration Information

• We have included a night time calibration OB for observations of a specphot
   standard star in IMG mode with the three narrow band filters.
  
  Twilight skyflats with no polarimetric optics in should be taken in the three narrow
   band filters (OII+44, SII/4500+64, SIII+65)
