Spectral Format

TripleSpec is a cross-dispersed spectrograph featuring five spectral orders, spanning 0.94 - 2.46 microns, which are represented by distinct X-Y loci projected onto the science detector. In photometric terms, one can think of each spectral order as being approximately equal to the 2MASS-like JHK filters, and the Y-filter, viz, K=3, H=4, J=5, Y=6/7 (see the figure below). The start and end-point wavelengths are shown for each spectral order.
