|HST Call for Proposals and Primer|
Please submit well before the deadline whenever possible, to avoid possible last-minute hardware or overloading problems, or network delays/outages. Late proposals will not be considered.
We strongly recommend that proposers start preparing their proposals early in order to give themselves enough time to learn APT. However, APT will not be made available/released for Cycle 21 Phase I use until mid-January 2013. If you need a version prior to the formal release, please send your request to the STScI Help Desk, firstname.lastname@example.org.Questions about policies and technical issues should be addressed to the STScI Help Desk (see Section 1.5) well before the deadline. While we attempt to answer all questions as rapidly as possible, we cannot guarantee a speedy response in the last week before the deadline.7.1.2 Phase I Proposal FormatCycle 21 proposals must be submitted electronically. A Java-based software tool, APT (the Astronomer’s Proposal Tool; see Section 1.4.5) is the interface for all Phase I and Phase II proposal submissions for HST.Both are submitted to STScI directly from within APT. Student Principal Investigators should also arrange for a certification letter to be sent by their faculty advisor (see Section 2.3.3).Please study Chapter 7, Chapter 8, and Chapter 9 carefully. We recommend doing so well before the submission deadline, to give the STScI Help Desk (see Section 1.5) ample time to answer any questions you may have.There are page limits on the size of your PDF attachment. Table 7.1 outlines these limits for different proposal categories.Table 7.1: PDF Attachment Page Limits
For Calibration GO (Section 3.2.4), Joint HST-Chandra (Section 3.5), Joint HST-Spitzer (Section 3.6), Joint XMM-Newton (Section 3.7) and Joint HST-NOAO (Section 3.8) Programs, determine whether your proposal is Small, Medium, or Large based on the HST orbit request, and use the appropriate page limits.
