Lucy Ralph LEISA Calibration Collection

Data Set Overview
===============================================================================
This collection consists of calibration products used in the calibration of
LEISA data products. The calibration products fall into one of four categories 
space background files, bad pixel maps, wavelength maps, and radiometric calibration
coefficient files. The application and use of the files is described in the 
SIS and Calibration Procedures documents found in the document collection of 
this archive. Note that Fringe files are used in the post calibration fringe corrections.

Data Products 
===============================================================================

Space Files
----------------
	These files are used to subtract the space background from raw image files.
    
Bad Pixel Map (BPM) files
---------------------------
	These file are used to correct for bad pixels on the detector array.

Wave Map Files
------------------
	These files contain the derived wavelengths for the full detector array.

Radiometric Calibration Coefficient Files
-----------------------------------------
	These files give the radiometric conversion factors for each image. 

Fringe Files
------------
	These files are used for the post calibration fringe correction.
