A new script named Astrometry Thermoelastic Drift Correction has been incorporated to the General Useful Scripts category. This is aimed at estimating astrometry shifts induced by thermoelastic drifts. These appear when an observation is performed at 'warm' attitude conditions (Star Tracker 2 temperature > -15 C). The script calculates the average temperature of STR2 sensors during the mid-point of the observation and, if that is > -15 C, it uses an established STR2-Z-axis offset correlation function to get the Z-axis offset and derive RA and DEC offsets. Two possible outputs are provided.

  • A new pointing product that takes into account the updated rotation matrix/quaternion and corrects the filtered attitude. This product can be used by the user to reprocess the observation.
  • New Level 2 products (only applicable to Photometry) where the offsets in RA y DEC (derived from the Z-axis offset) have been used to adjust the WCS.

Tasks

  • The Applicable node of the Tasks view is opened by default, so tasks applicable to the current selection are more directly visible.
