linearmosaic.defineoutputimage - Function

3.1.3 Set the output direction image parameters and name


Description

Define the direction axes output image parameters. The output image will get the same number of spectral and polarization planes as the input images. This function create a fresh new output image. If an image of the same name exist on disk it will be erased. The spectral and polarization part of the image will be identical to the images that are being mosaiced.

The output image will by default be flux correct and the weight image will be pAp2(θ) where the primary beam is Ap(θ)
