PPLOT -- Plots slices of a data frame in either X or Y direction.
PPLOT is useful for quick examination of 2D data, determination of bias
regions, good data regions etc.
Parameters:
IMAGE -- The data in question. Note that if you want to specify
a subregion then put e.g. 'run356(1:20,400:500)' or
'flat(~100,~100)' to get central 100 by 100 region
etc. See NDF help for more details on this. The
old method prompting for a region is still enabled if
you specify a plain file.
XSTART -- Lower X limit (if no section defined in IMAGE)
XEND -- Upper X limit (if no section defined in IMAGE)
YSTART -- Lower Y limit (if no section defined in IMAGE)
YEND -- Upper Y limit (if no section defined in IMAGE)
DIRN -- If 2-D data, what direction to plot slice, X or Y?
AUTO -- Plot limits are set automatically from the data or not.
LIMITS -- Plot limits.
DEVICE -- Plot device. This will be ignored if one is already
open.
History:
NDF version created 08/01/1998 by TRM.
Changed to account for specification of region through NDF section
as well as old method.
