Space Telescope Imaging Spectrograph Instrument Handbook for Cycle 22 > Chapter 10: Summary and Checklist > 10.2 Phase II—Scheduling Approved Observations

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 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.
