It is essential that observers proposing to use the SBC read and abide by the procedures and rules described in Section 4.6
and Section 7.2
. Designing safe observing programs will protect the MAMA detectors in the SBC from being damaged by over-illumination. We therefore ask all users to share the responsibility of STScI to ensure the safety of the MAMA detectors. All proposed SBC targets and fields must be discussed in the Phase I proposal, so that their feasibility can be assessed by the TAC and STScI.
