10.2
Below, we provide a checklist for observers filling out Phase II proposals. You should do the following prior to submitting your program.
For All Proposals:
Specify your coordinates (especially for spectroscopic observations) in the Guide Star reference frame. Be sure to specify the coordinate source used. If your target has significant proper motion, be sure to also include this information in the appropriate fields in the Phase II proposal file. Check that the units of the proper motion are correct, and that the epoch specified is consistent with the coordinates supplied.
Specify accurate V magnitude, fluxes, spectral type, and colors for your target. This is required for MAMA targets to allow for bright object checking. If you are using the MAMAs and have UV photometry (e.g., from GALEX) for your target, provide it.
Specify accurate V magnitude, fluxes, spectral type, and colors for your ­target. This is required for MAMA targets to allow for bright object screening.
Verify the correct usage (i.e., direction) of your PATTERN optional requirement or POS-TARGs (if used).
Check the Phase II webpage for any updates. You can also find there instructions for requesting changes to your program and observing policies.
For CCD Observations:
CR-SPLIT CCD exposures, as appropriate. Keep individual exposure times < 1000 s if possible to avoid excessive cosmic ray events.
Add fringe-flat exposures for G750L and G750M observations at λ > 7500 Ĺ.
For MAMA Observations:
For TIME-TAG observations, verify the value for BUFFER-TIME.
Consider the use of stepping along the slit for first-order modes or the use of FP-SPLIT slits for echelle modes, when high signal-to-noise is required.
