Process POINTING observations in the summit pipeline


This recipe processes data from a POINTING observation in the SUMMIT pipeline.

For DREAM/STARE, the images from the individual subarrays are combined, sky emission removed (assuming a simple DC offset) and corrected for extinction.

SCAN-mode data are passed to the iterative map-maker. Fast-ramp flatfield files are processed and stored so the iterative map-maker can use them.

The image is cropped to 150 arcsec on a side, and if the source is a known calibrator, the pipeline calculates FCFs. The map is then calibrated and tagged as a reduced product.

For additional record keeping, the source position is fitted and offsets in Azimuth and Elevation from the nominal (0,0) position are derived and logged. Note, however, that these may not be identical to those derived by the telescope POINTING_FOCUS task.

This recipe is largely the same as REDUCE_POINTING with minor modifications specific to handle data as they are taken.



The coadd is displayed in Gaia window 2; its variance is displayed in window 3.
