Hubble Space Telescope Call for Proposals for Cycle 11

8.17 Special Requirements

---

(This is item 16 in the GO/SNAP template; it does not appear in the AR/Theory template.)

List and justify any special scheduling requirements, including requests for:

• Target of Opportunity (TOO) observations. For TOO observations, estimate the TOO's probability of occurrence during Cycle 11, and state how soon HST must begin observing after the occurrence (see Section 4.1.2).
• CVZ observations (see Section 4.1.1).
• Shadow time or Low-sky observations (see Section 5.5 of the HST Primer).
• Time-critical observations (see Section 4.1.4).
• Early acquisition observations (see Section 5.2.1 of the HST Primer).
• Target acquisitions that use the `Reuse target offset' function (see Section 5.2.2 of the HST Primer).
• Real-time interactions (see Section 4.1.5, and Section 2.6.1 of the HST Primer).
• Scheduling of STIS/MAMA and STIS/CCD observations (other than target acquisitions) in the same orbit (see Section 6.2.3 of the HST Primer).
• Scheduling of NICMOS coronographic observations in the same orbit with a roll of the spacecraft between observations (see Section 6.2.3 of the HST Primer).
• Other special scheduling requirements (e.g., requests for non-SAA impacted observations).

Also, if applicable, discuss the benefits of or need for a non-default proprietary period request (see Section 5.1 and Section 8.10).
