Type: Adverb (real scalar)
Use: To specify how many pixels are ignored around the edges of an
image. This is equivalent, for a single image, to
BLC = 1+EDGSKP, 1+EDGSKP, 0
TRC = maxx - EDGSKP, maxy-EDGSKP, 0
Null value: <= 0
Taken to mean include all pixels.
FLATN......Regrids a set of IMAGR fields onto a single image
geometry. EDGSKP rows and columns from the edges of each
field are not included.
DDT........Standard software and perfomance suite. EDGSKP pixels at
the edges of the images are NOT compared. Usual values: 4
for Small, 8 for Medium and 16 for Large DDT RUNs.
