| grism = none, g1, g2, g3, e2
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, none
binning = 2x2, 1x1, 1x2, 2x1
|
|---|
g1 should use the GG385, OG475, OG515, OG590 filters
g2 should use the GG385 filter
g3 should use the OG515 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.
