3. 3 PPS Architecture Overview

4. 4 APT/ETC History Both started as a Goddard prototype called the Scientist’s Expert Assistant (SEA).  STScI provided science direction  Goddard & Goddard contractor’s built the prototype  1998 to 2001 (approximate timeframe) HST takes SEA & builds upon the concept  APT/ETC released in 2002 (cycle 12) for operational use  Over the years, we replaced many portions of the original code & brought the code up to production standards.  Code from the original prototype is still used operationally today ETC used by HST, & will be adapted for JWST APT used by HST, SOFIA, & will be adapted for JWST

5. 5 HST ETC Trade Study In the fall of 2006, we carried out a study of how we would implement ETCs for JWST (JWST-STScI-000912)  Concluded that the HST architecture for ETCs are usable for JWST  Defined a general set of algorithms for use in sensitivity calculations  Assessed how background effects would be incorporated into these calculations

6. 6 HST APT Trade Study In the fall of 2005, we carried out a study of how we would implement the Proposal Definition Tool for JWST ( JWST-STScI-000518 )  We compared APT to Spitzer’s Tool (Spot)  We worked with Spitzer’s Team Lead (Trey Roby) to do a functional comparison  Both tools were very similar in features  APT had a few more capabilities and we felt that it would be less cost to modify

24. 24 Grants Management System Maria Bertch

25. 25 Programs & Grants Accepted Science Program 1  For each science program there is a budget  For each budget there can be 1 or more grants  1 investigator per grant (US investigators only)  Each investigator submits & manages their own grant Accepted Science Program N STScI Grants Office Manages Thousands of Grants

27. 27 STGMS Functionalities STGMS is made up of two main software applications. STGMS – External System Used by institutions and investigators to submit budgets, monitor their grants, submit reports and process other grant requests, etc. STGMS – Internal System Used by the STScI Grants Administration staff to process grant actions, monitor grants and prepare for financial review of requested budgets. It is also used by Accounting staff to process payment requests from grantees.
