Tutorials for UVCS/SOHO Data Analysis
UVCS/SOHO data is processed in three major steps:
-
Spectral Data Files
are read by the UVCS Display and Analysis Software
(DAS)
package, and can be calibrated in wavelength and intensity,
in addition to being
corrected for image distortion, detector flat-field, and dark counts.

-
Processed Spectral Data Files
are then corrected to separate instrumental from astronomical sources.
In intensity, disk-scattered stray light and interplanetary emission
are removed.
In wavelength, instrumental broadening, point spread functions, and
intrinsic quantization errors are removed.

Science Data Files are then analyzed by comparing with results
of theoretical radiative-transfer codes.
This ``empirical modeling'' provides densities, abundances, and
velocity distribution parameters.
