ISPI Filters
ISPI is offered with the broad band Y, J, H, Ks filters, as well as a set of narrow band filters. Basic data are given in the tables below. Filter scans are available for some of the filters here.
Fluxes, isophotal wavelengths, and isophotal frequencies for Vega have been determined by Tokunaga and Vacca for J, H, and K' filters which comprise part of the MKO/Gemini filter set. Copies of these filters were used in ISPI up until 2004B.
