" Hectospec is a moderate-resolution fiber-fed spectro-
meter on the modified 6.5-m MMT of
the
Smithsonian
Astrophysical Observatory.
Of the several grating configurations of Hectospec, we choose the one with a
270 groove/mm grating and a blaze angle 5 = 5.3°. To simplify our exercise we
choose Eq. (15.2.2) rather than the more accurate Eq. (15.2.1); for this grating the
error mad ...
