Help for RESSAR75

PURPOSE:

"ressar75" is a VICAR applications program which removes the reseau marks
and camera blemishes from Viking Orbiter images.

EXECUTION:

	ressar75 INP=(A,RES) OUT=B user-parameters...
where

	A is the input Viking Orbiter image,
	RES is a reseau location record generated by program RESLOCVO
            containing the reseau locations for image A.
	B is the output image, with reseau and/or blemishes removed.

The input image must be in standard VO format (1204x1056 with no geometric
correction applied).  The entire image is processed (i.e. no size field is
accepted).  The input may be in byte or 16-bit integer format.  The output
will be in the same format as the input.

OPERATION:

Each reseau mark is removed by interpolating over samples a specified radius
(see RADIUS parameter) from its center, as defined in the reseau location
record RES.  Each camera blemish (see VO Calibration Report) is similary
treated, with their centers and radii retrieved from tables built into the
program.

The keywords KEEPRESE and KEEPBLEM may be used to suppress removal of either
reseau or blemishes.

The CENTERS parameter may be used to specify circular areas of the image
to be interpolated over.

Because line 1 of all Viking Orbiter images is normally saturated, it is
not processed, and is simply copied to the output image.

EXAMPLE:

	reslocvo A RES
	ressar75 (A,RES) B

Program "reslocvo" is used to locate the reseau and store the line-sample
coordinates of each reseau mark in RES.  "ressar75" is then used to remove
the reseau and camera blemishes.
