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. Tasks: 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. Procedures: 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. ----------------------------------------------------------------
