Descripción
Procedures were developed for extracting low resolution spectra while
correcting for halation effects and scattered light within the
instrument. To correct for halation, the spectra were extracted from the
line-by-line images. Perpendicular scans of the image were fitted using
an iterative least squares procedure with a known form function. The
fitting function was a linear combination of a Gaussian with a Lorentz
function. Correction for light scattered from the gratings employed a
guess and test method. A priori choices of schematic spectral
distributions were used to compute different sets of scattered light
coefficients. Satisfactory results are shown for both methods.
