[55.06] Sensitivity of MOSES to Chromospheric Spectral Line Profiles

C. C. Kankelborg (Montana State University)

The Multi-Order Solar EUV Spectrograph (MOSES) is a new type of slitless imaging spectrograph with detectors at three spectral orders (-1, 0, 1). The slitless configuration allows collection of spectroscopic information simultaneously over a 2D image. This study assesses the information content of an idealized MOSES data set by deriving and analyzing the null space of the instrument response. The conclusion is that MOSES is sensitive to line intensity, line width, and doppler shift but is insensitive to higher moments of the line profile. Addition of detectors at higher orders would impart sensitivity to line asymmetry and higher moments.

This work is funded by NASA Grant NAG5-10997.
