ARRAY_TESTS - Calculates the readout noises and dark current for UFTI

Description:

This script calculates for UFTI the NDSTARE readout noise, and the dark current from a series of four engineering frames taken with the sequence called array_tests. The results are compared with the nominal values, and you are notified whether or not the values obtained are within limits. At UKIRT, the results are also logged to an engineering file for archival purposes.

Notes:

• Intermediate frames are deleted.

• The engineering log contains the UT date and time, the NDSTARE readout noise and the dark current. The results are normally appended to the log. If for some reason it does not exist, a new log is created containing the column headings.

• Multiple array tests are permitted. A new set of results is reported and logged for each cycle.

• The NDSTARE readout noise is filed in the calibration system.

Output Data :

• The engineering log $ORAC_DATA_OUT/ufti_array_tests.log.
  

Implementation Status:

• The processing engines are from the Starlink package KAPPA.

• Uses the Starlink NDF format.
