REDUCE_SCAN_EXTENDED_SOURCES

Process SCAN data from extended sources

Description:

This is the recipe for processing SCAN data for extended (e.g. Galactic) sources. The makemap configuration file is tuned to best deal with such data.

Raw data are passed to the map maker which are processed to produce a Frame image, which is then calibrated and displayed. A new Group image is created and displayed. The noise properties of the new Group image are calculated and written to a log file, log.noise.

Notes:

The current noise level is stored in log.noise.
For large amounts of data this recipe will spend a long time not updating the ORAC-DR output. Check to see that makemap is still processing by running top or ps.
Alternative configuration parameters for the iterative map-maker may be specified using the recipe parameters outlined below.
The output map is calibrated in units of mJy/arcsec $*$ $*$ 2.

Available Parameters :

The following parameters can be set via the -recpars option:

MAKEMAP_CONFIG

Name of a config file for use with the SMURF makemap task. The file must exist in the current working directory, $MAKEMAP_CONFIG_DIR or $ORAC_DATA_OUT.

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.
