Tools for planning future observations

Tables of candidate standard stars

This is the full list of potential standards (updated 21 Oct 04).

S/N calculator (Excel spreadsheet)

This spreadsheet will give the S/N for a single ramp as a function of wavelength and integration time for each module. The user needs to input the flux of the source (in mJy). The blue template extrapolates all fluxes from 12 um using a Rayleigh-Jeans tail. Enter the IRAS 12 um flux (as given in the PSC, i.e. not color-corrected); the fluxes at 25, 60, and 100 um are not used. The red template makes linear interpolations using the entries for 12, 25, and 60 um. The value in cell E9 is the linearly extrapolated flux at 5 um. If it's positive, enter this value in cell E5; otherwise, enter a better estimate in cell E5.

Observing schedules for IRS campaigns in normal operations:

• 6 observations per day, conservative approach (used for Campaign 1)
• 6 observations per day, standard approach (used for Campaigns 2 through 4) (updated 19 Nov 03)
• 4 observations per day
• 3 observations per day (used for Campaigns 5 through 9)
• 2 observations per day (used for Campaigns 10 through 16)
• long-campaign schedule (used for Campaigns 17 through 20)
