3 PPS Architecture Overview

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 HST ETC Trade Study In the fall of 2006, we carried out a study of how we would implement ETCs for JWST (JWST-STScI )  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 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 )  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

17 Astronomer’s Proposal Tool Tom Donaldson

18 Uses of APT PIs use APT to prepare HST proposals for review and implementation. STScI scientists and engineers use APT to prepare calibration & engineering programs for HST. STScI operations staff use APT to help validate and maintain programs. PIs use APT to prepare proposals for the SOFIA Observatory.

24 Grants Management System Maria Bertch

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

26 Grant Administration PI Submits Budget Peer Review of Budget Grant Awarded PI Gets Time on the Observatory YEAH! Grant Closeouts STScI Requests Budget Grant Process (cradle to grave) STScI Notifies PI about their Funding STScI Director Review & Approval Grant Reporting & Mods Distribute Funds Budget Preparation & Review Process Investigator moves to new Institution Grant Management Process

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.

47 GMS Interface to PPS DB JWST PPS Database (SQL Server) (Sybase) Program Data & Execution Status GMS Nightly Extraction of Program Data & Execution Status

48 GMS Modification for JWST GMS needs data from the JWST PPS database.  Data extracted (investigator information, time allocation, status of observations…)  This process is run nightly to keep existing grants up to date and to create new grants as new science are awarded.  Code to modify grants based on program status (executed, failed, withdrawn)  JWST PPS data will be from SQL Server DB not Sybase DB Updates to the External System to allow investigators and administrators to select their JWST grants
