CLEAN-Interactive patching of bad lines, bad pixels in an image

Description:

CLEAN is an interactive routine for fixing bad pixels and rows in CCD data. CLEAN can be used either as a prelude to BCLEAN, in order to see what parameters may be suitable or else it may be used after BCLEAN, to patch up any rows or pixels that BCLEAN missed.

Parameters:

IMAGE

IMAGE is the image - usually a CCD image - that is to be interactively cleaned of bad rows and bad pixels. Note that the orientation of the image data should be such that bad rows are horizontal (as seen on the Grinnell).

OUTPUT

OUTPUT is the name of the image that results from the cleaning process. If OUTPUT is the same as IMAGE (the default value) the correction will be performed in situ.

QUIT

Used to confirm quitting the application.

DEG

Degree of fit to use for interpolation.

XSIZE

Size of deletion box in X.

YSIZE

Size of deletion box in Y.

HIGH

Highest displayed data value.

LOW

Lowest displayed data value.

 C L E A N

 Main routine for the Figaro 'CLEAN' command.  Displays
 a CCD image and then allows the user to move around it with
 the cursor, selecting rows and columns to be corrected and
 cosmic rays to be zapped.  The idea is that this routine can
 be used to fix up any areas in an image that were not fixed
 automatically by the non-interactive version ('BCLEAN').  It
 may also give a better idea of the best settings for the
 BCLEAN parameters.

 Command parameters -

 IMAGE      (Character) The name of the image to be displayed.
 OUTPUT     (Character) The name of the resulting cleaned image.
            If the same as IMAGE, the image is cleaned in situ.
 QUIT       (Logical) Used to confirm quitting the application.
 DEG        (Integer) Degree of fit to use for interpolation.
 XSIZE      (Integer) Size of deletion box in X.
 YSIZE      (Integer) Size of deletion box in Y.
 HIGH       (Real) Highest displayed data value.
 LOW        (Real) Lowest displayed data value.

 User variables -  ("<" output, "!" modified)

 (!) IMARRAY (Numeric array) Contains current image display
             parameters.
 (<) IMFILE  (Character) Contains name of currently displayed
             image file.
 (>) IDEV    (Character) Contains name of display device.
