Define gradient derived fields in spectral space:
SPCGRAD
Set range of spectral bandpassing (A,B):
SPCBPcn
Fields deleted before return to gridpoint space:
SPCDFcn
Fields excluded from spectral processing (A,B):
SPCEFcn
Define fields as vector pairs:
SPCVP
Control spectral data form:
SPCTAVV
SPECTRAL PLOTTING:
Control spectral graphics:
SPSNGRF
Control y-interval range on spectral graphs:
SPGYINT
SPECTRAL DERIVED FIELDS:
