MASK/IRAC2 inframe outframe
	replaces bad pixels by closest good pixel
\us\pu
Purpose:     
	     Replace each bad pixel by closest good pixel.

Syntax:      
             MASK/IRAC2 inframe outframe
\ys\pa
             inframe     = name of image file which is to be cosmetically
                           treated by replacing bad pixels by neighbouring
                           good pixels.
\ap\pa
             outframe    = name of resulting file which contains the 
                           clean image having all bad pixels replaced.
\ap\no
Note:        
             The pixelmask is stored in file GOODPX.bdf which has to be
             created by the MIDAS command CMASK/IRAC2 in the current
             directory. Good pixels are marked by 1 and bad pixels are
             marked by 0 in file GOODPX.bdf.
\on\exs
Examples:
\ex
             MASK/IRAC2 spiral spiralclean 
             The bad pixels of the frame spiral.bdf are replaced by
             neighbouring good pixels using the pixel mask GOODPX.bdf
             which has been created by the midas command CMASK/IRAC2.
             The clean image is stored in the frame spiralclean.bdf and
             displayed using the cut levels of frame spiral.bdf.
