20.2 FEATHER

[ADVANCED\]FEATHER [?] [/FILE Combined HIGHRes LOWres] [/REPROJECT]

Combines a data cube containing High resolution data (HIGHres) with one containing the short spacing data (LOWres). Automatic reprojection and spatial resampling of the LOWres data may be done if the option /REPROJECT is specified.

The method is to hybridize in the UV plane the data, retaining short UV spacings from LOWres and long UV spacings from HIGHres. It is controlled mainly by variable FEATHER_RADIUS, the transition radius, and FEATHER_EXPO, an exponent controlling the transition sharpness

Other variables allow some flux re-scaling or verification.
