JITTER_SELF_FLAT_NO_MASK

Reduces a “standard jitter” photometry observation without object masking

Description:

This script reduces a “standard jitter” photometry observation with near-infrared imaging data. It takes an imaging observation comprising jittered object frames and a dark frame to make a calibrated, untrimmed mosaic automatically.

It performs a null debiassing, bad-pixel masking, dark subtraction, flat-field creation and division, feature detection and matching between object frames, and resampling. See the “Notes” for further information.

This recipe works well for faint sources and sparse fields.

Notes:

Output Data

Parameters:

NUMBER = INTEGER
The number of frames in the jitter pattern. If not supplied the number of offsets, as given by FITS header NOFFSETS, minus one is used. If neither is available, 9 is the default. An error state arises if the number of jittered frames is fewer than 3. For observations prior to the availability of full ORAC, header NOFFSETS will be absent. []
USEVAR = LOGICAL
Whether or not to create and propagate variance arrays. [0]
