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])
