deconvolver.makeprior - Function



Package general
Module deconvolver
Tool deconvolver


Make the mem's prior image, or make a mask


Synopsis
makeprior(prior, templateimage, clipfrom, clipto, blc, trc, async)


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.



Arguments

prior   output prior image
    Allowed: String
templateimage   starting point for prior image
    Allowed: String
clipfrom   Clip any pixel below this level
    Allowed: String
    Default: '0.0Jy'
clipto   Any clipped pixel will be given this value
    Allowed: String
    Default: '0.0Jy'
blc   Bottom left hand corner for box; outside box is clipped
    Allowed: integer[]
trc   Top right hand corner for box; outside box is clipped
    Allowed: integer[]
async   Run asynchronously in the background?
    Allowed: Bool
    Default: !dowait



Returns
Bool


Example
deco.makeprior(prior='3C283XC1.prior', templateimage='3C283XC1.mem.smooth',
clipfrom='0.01Jy', clipto='0.0001Jy', blc=[100,100], trc=[150,150])
