deconvolver.makeprior - Function

3.1.2 Make the mem’s prior image, or make a mask

Description

Makes a prior image for the mem function. A general way to make a prior image is to start with a low resolution image, obtained from a smaller array configuration or a lower frequency observation, from another image which has been smoothed, or from a single dish image. The low resolution image can then be doctored via clipping and regioning to make it acceptable for the mem function.

Currently, only one Stokes parameter may be used at a time.
