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-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

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

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.

19APT is supported on Linux, Mac, Windows and Solaris.

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

STGMS FunctionalitiesSTGMS 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.

28

STGMS Architecture

External system used by investigators and administrators

Internal system used by STScI

One system linked by web services and database

Two Parts of the Same System

GMS Statistics

Number of grants in GMS (since 5/1/00): 6439 Number of active grants: 2023 Number of institutions that can receive grants: 403 Number of institutions with awarded grants: 341

It takes ~50 transactions to process a grant from inception to closeout (i.e. create and pre-populate grant, budget submission, award process, reports, documents, special requests, check issuance, etc)

~ 321,905 transactions handled by the Grants Office since 5/1/00

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

49

GMS Modification for JWST(con’t)

Changes to track JWST time vs. HST orbits. Reporting changes Database changes

Develop reports needed specifically for JWST

Create user help for JWST GMS

Create regression tests for JWST
