We determined the throughput measurements of COSMOS by obtaining spectrophotometric standard star data with the individual grisms. The data were reduced and calibrated using standard IRAF routines. The High-Resolution Blue Grism (hb4k) and the additional slit configurations will be measured during the May 2018 engineering block.
The throughput curves can be downloaded here.
