Spatial Profiles


Below we provide encircled energy tables for each grating mode. Included are the values for the fraction of the total flux contained in the default point source extraction aperture (not the same as the physical aperture) during pipeline processing. calstis, the pipeline code, sums a number of pixels to obtain the spectral fluxgiven by the "Extraction Height." These tables also give the fractional flux in the peak pixels. Accompanying figures show sample spatial profiles (i.e., in the direction perpendicular to the dispersion).
