ARRAY_TESTS

Description:

Basic processing recipe suitable for DREAM/STARE images from a single subarray. This recipe is designed to be used for lab-testing only.

No alignment is done on the images so that they are mosaicked in the pixel frame (this means that if data exists from multiple subarrays, they will be averaged together!). A method to determine the frame-to-frame variance is provided which writes out to a log file called log.noise which can be monitored by the StripChart. The relevant column to monitor is " noise" .

Notes:

• This primitive is not designed to handle time series observing modes.

• If the frames are identical, then the Group mosaicked image with contain " NaN" . In that case, add the argument GENVAR=0 to _MAKE_MOSAIC_FRAME_.

• If there is no variance, " NaN" will be written to log.noise. The stripchart may or may not do something sensible with that.

• The Group image variance is written to log.noise for monitoring with the StripChart.

Display

The Frame image is displayed in Gaia window 1. The Group image is displayed in Gaia window 2; its variance is displayed in window 3.
