Determining the Spectral Content of MOSES Images
Abstract
The MOSES (Multi-Order Solar EUV Spectrograph) sounding rocket was launched February 8th, 2006. The MOSES concave grating forms solar images in multiple spectral orders, in an effort to measure line profiles from a single exposure over a wide field of view. We present a preliminary identification of spectral content in MOSES images. The cross correlation of subtracted images provide evidence of spectral content besides the normal 304 Anstrom He II line. We place confidence on the peaks in correlation by cross correlating random data that is statistically representative of MOSES data. These significant peaks indicate a contribution to intensity from several coronal lines. These lines are individually weak, but if not taken into account, they would significantly increase the residuals when inverting MOSES images to obtain spectra.
