Estimated Total Execution Time (hours, including overheads)

• 1.0 hours

General Description

• This is a simple imaging run with repeated jitters of the same star field.
   This image will be used for astrometric determination of proper motions and parallaxes
   of all stars in the field. The field center is shown in Finding Chart

Waiver Requests

• The Waiver Request (78.C-0074A.01.WAV, submitted on 14.07.06, APPROVED
   on 19.07.06) concerns constraints
  on Local Siderial Time (LST) for execution of OB. An objective of the Observation
  Programm is the ultra high-accurate astrometric determination of proper motions
  and parallaxes from coordinated observations, evenly spaced in time.
  The results are strongly affected by the differential chromatic refraction
  of the atmosphere, the latter being a function of hour angle,
  or LST of the observation. For the success of the Programm, it is
  critically important to execute runs of different nights at approximately equal
  LST and not far from the meridian. To be coordinated with other runs,
  I ask, if possible, to shedule start of this run
  at LST within the limits of 6 h 10 min and 7 h 30 min.

Critical Observing Condition Constraints

• Observations of faint stars - avoid full Moon illumination (gray conditions).
   Clear sky and
  0.8" seeeing.

Time-Critical Aspects

• Proper motion and parallax determination from observations, evenly spaced
   in time. To be coordinated with other runs,
  I ask to execute this OB in the time window from 2006-nov-13 to 2006-nov-29.
  Ultra high-precision astrometry requires correct reduction of atmospheric chromatism.
   Therefore it is important to execute this run near meridian, starting its
  execution at Local Siderial Time in the range from 6 hours 10 min to 7 hours 30
   min
  (this time constraint was approved with a waiver request 78.C-0074A.01.WAV).

Special Execution Requirements

• Please write the position of the LADC in the night report. This is an
   important parameter used in the reduction.
