Use this procedure to read the SIR-C header information used by other SIR-C routines.
Syntax
SIRC_HEADER_DOIT [, AZ_KM=variable] [, BAND=variable] [, CANCEL=variable], FILENAME=string [, NL=variable] [, NS=variable] [, OFFSET=variable] [, RANGE_KM=variable] [, SLH=variable] [, TYPE=variable]
Keywords
AZ_KM (optional)
Use this keyword to specify a named variable that contains the azimuth or y image size in kilometers.
BAND (optional)
Use this keyword to specify a named variable that contains the band number for the file specified by FNAME. Set BAND to 0 for C-Band data and to 1 for L-Band data.
CANCEL (optional)
Use this keyword to specify a named variable that will be set to 0 if you cancel the read request.
FILENAME
Use this keyword to specify the filename of the SIR-C file.
NL (optional)
Use this keyword to specify a named variable that contains the number of lines in the SIR-C image.
NS (optional)
Use this keyword to specify a named variable that contains the number of samples per line in SIR-C image.
OFFSET (optional)
Use this keyword to specify a named variable that contains the offset for the file specified by FNAME.
RANGE_KM (optional)
Use this keyword to specify a named variable that contains the range or x image size in kilometers.
SLH (optional)
Use this keyword to specify a named variable that contains a flag indicating whether the file needs to skip the line header. A value of 1 indicates that the line header must be skipped when processing.
TYPE (optional)
Use this keyword to specify an named variable that contains the SIR-C data product type for the file specified by FILENAME.
