Below are documents that describe the throughput for MOSFIRE. The throughputs are based on on-sky measurements of standards acquired in May 2012, and in general, the measured and predicted throughput are in good agreement. The throughput of the instrument includes the throughput of common optical elements, configurable elements, and the detector QE. In each graph in the table below, the throughput for the instrument, instrument+telescope, and total throughput from the top of the atmosphere are plotted.
