Requests for the Gecko/CAFE tests of June 2000




1. Primary wavelengths, used to measure throughput and check line profiles.

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...



2. Secondary wavelengths, used to measure throughput

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...
