Command Line Usage
SeaDAS-Toolobox -> SeaDAS Processors -> l1bgen_generic
l1bgen_generic reads in a SeaWiFS Level-1A file (HRPT, LAC, or GAC) and generates a L1B file by applying the sensor calibration at the same resolution and location as the Level-1A data.

Usage: l1bgen_generic argument-list
The argument-list is a set of keyword=value pairs. The arguments can
be specified on the commandline, or put into a parameter file, or the
two methods can be used together, with commandline over-riding.
return value: 0=OK, 1=error, 110=north,south,east,west does not intersect
file data.
The list of valid keywords follows:

hdf4: output a HDF version 4 file
fqfile (ifile) (default=$OCDATAROOT/common/morel_fq.nc) = f/Q correction file
parfile (ifile) = par climatology file for NPP calculation
georegion_file (string) = geo region mask file with lat,lon,georegion 1=process pixel, 0=do not
