9.3 Special Requirements

---

(This item is required only for GO and SNAP proposals)

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

Target of Opportunity (TOO) observations. For TOO observations, estimate the probability of occurrence during Cycle 16, and state how soon HST must begin observing after the occurrence (see Section 4.1.2).
CVZ observations (see Section 4.1.1).
Time-critical observations (see Section 4.1.6).
Early acquisition observations (see Section 5.2.1 of the HST Primer).
Coordinated Parallel (CPAR) or Pure Parallel (PPAR) observations
Target acquisitions that use the ‘Re-use target offset’ function (see Section 5.2.2 of the HST Primer).
Real-time interactions (see Section 4.1.7, and Section 2.6.1 of the HST Primer).
Requests for expedited data access (see Section 7.2 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 8.7).
