This IDL software is used
for display and analysis of the science data. It can read and
write FITS format Spectral and Visible Light Data Files, display the 2D spectral
data, carry out the calibration procedures to correct for instrument
response, perform wavelength and pointing calibrations, and transform the
science data into physical units (
),
and perform some basic functions for measuring line profiles and
intensities. Software will also be available to transform a set
of spectra covering different radial and roll positions into images,
including the daily images to be provided to the Experimenters Control
System (ECS) as part of the Summary Data.
The Data Analysis Software will be used at various sites
including Experiment Operations Facility (EOF) and Experiment Analysis
Facility (EAF) at Goddard Space Flight Center, the Data Reduction and
Analysis Facility (DRAF) at SAO, the Italian and Swiss Data Centers, MEDOC,
and other co-investigator institutes. It is more fully described in
Data Processing Software Requirements for the Ultraviolet Coronagraph Spectrometer.
It will require the Calibration Files listed in the previous paragraph, as
well as the final Orbit/Attitude files supplied by NASA to determine the
pointing from the instrumental parameters and to wavelength and flux calibrate
the Spectral Data Files.
