This document describes the data files that may be read into th edata analysis software.
Several file formats are recognized by the HESSI data analysis software: FITS, SMEX, ITOS, GSE, RAW.
The FITS file format is usually used for data analysis. It is the default format. The FITS files are recognized by their extension .fits, .fit, or .fts.
HESSI FITS files consist of several binary tables.
The SMEX file format allows to read HESSI data into IDL directly as they come out of the Ground Station. This is the fastest way of reading data once it has been telemetered to the ground.
The ITOS file format allows reading data after it has been gone through the ITOS system. This mode may not be used very often.
The GSE files have been recorded using the Ground Support Equipment. This is used mainly for reading spectrometer calibration files.
The RAW data files are thos that contain only the packt data
