Image Details
Caption: Figure A1.
Convolution of the COS LSF with varying spatial FWHM: original (green), narrow (blue), and wide (red) for the YSC M83-POS-1 (visit - LDN 701010, PID: 15193, PI: Aloisi). The range in spatial FWHM is obtained from the structure within the 1D acquisition image. The separate subplots show some of the different wavelength regimes available in HST/COS spectra.
