Setup has to be done as carefully as if for science observations.
Central Wavelength |
Order | Filter/Grism | Line(s) observed |
---|---|---|---|
3950 Å | 14 | UV Grism | Ca II H & K lines at 3934 Å and 3968 Å |
4860 Å | 11 or 12? | Blue Grism | H Beta at 4861 Å |
5890 Å | 9 | Blue Grism? #1519? | HeI at 5876 Å, NaI D1 & D2 lines at 5890 Å and 5896 Å |
6565 Å | 8 or 9? | #1617? #1626? | H Alpha at 6563 Å |
7700 Å | 7 | #1704 | K line? |
8660 Å | 6 | #1814 | A line of the CaII IR triplet at 8662 Å |
Still looking for stars + wavelengths above 10,000 Å... |
Setup does not have to be perfect; we can just trust the `gs' script. These values will help get a detailed Throughput Table.
I'm mainly following Tables 6 and 8 of the Manual...
