grism = none, g1, g2, e2 (g3 is now offline) slit = none, 1.0, 1.5, 2.0, 3.0, 10.0 all 4 arcmin long and the mos unit. filter = B, V, C, R, I, z, GG385, GG475, OG515, OG590, E2F | ||
G2 should use the GG385 filter E2 should use the E2F filter C (cyan) is Phillip MacQueen's B+V filter (3mm GG385 + 3mm BG39). |
For those unfamiliar with Schott Glass blocking filters, the number in the name is the approximate half-power point of the transmission cut-on in nm.
