## XMM-Newton GOFOverview

- XMM Newton is a major joint ESA-NASA X-ray astronomy satellite with ESA responsible for construction of the satellite, mission operations, and data processing.
- Two US groups have made substantial contributions to the instruments, Columbia U. (PI Kahn) for the RGS and UCSB (PI Cordova, now at UC Riverside) for the OM.
- The US guest observer program is supported by the GOF at Goddard Space Flight Center (US Project Scientist Mushotzky). This is also the site of the US archive
- More than 215 papers accepted in refereed journals so far.
- XMM-Newton is in its operational phase, with most of the data going to the GO community worldwide

## US Participation in XMM

- HARDWARE
-    	RGS (Columbia U),  OM (UC Riverside previously UCSB, Sandia, LANL)
- SOFTWARE
- 	System support and programmers at GSFC => user support and general analysis tools, e.g., port to OSX, maintain Redhat 6.2, support of some tasks, support of the DTS, some Ftools, QuickSim, scrsim
- GO SUPPORT
- 	GOF (at NASA/GSFC) and E/PO (at the GOF and Sonoma State)
-  SCIENCE
- 	US astronomers on ~66%  accepted proposals, ~50% of those proposals have US PIs

## XMM-Newton – Mission Status

- The satellite and all instruments are performing well, and on course for a 10 year mission lifetime(expendables 15-20 years).  Observing science window is 80.5% of total, true science observations use ~60% of that time.
- Operating temperatures for EPIC MOS and RGS detectors have been lowered (data much cleaner)
- Delta V maneuver completed removing the perigee gap => more science time
- ESA has approved a four year mission extension for XMM-Newton with a budget review next year
- Data processing and distribution is now nominal with about one month of separation between an observation and the delivery of the data.  There have been over 2134 routine phase (> orbit 103) performed observations (through 20 November 2002).

## XMM-Newton – AO Status

- Proposal reviews for AO-2 took place in 2002 May-July with a completion date in July
- There was considerable US scientist participation in the review
- AO-3 is scheduled for release March 18th with a close in late April.
- GT and AO-1 observations are nearly complete, AO-2 observations have begun (and GO funds are flowing).
- AO-3 and AO-4 will last ~15 months to remove the synchronization of the Chandra and XMM proposal cycles.
- R. Griffiths (chair of the US users group) and R. Mushotzky (US project scientist)** **represent the US in the European Users Group.** **

## XMM-Newton Software Status

- Mission software for scientific analysis (SAS) fully functional and robust.  SAS is a EU development (SSC and ESA) with US GOF programmer and systems support
- SAS is a standalone system with its own libraries and GUI, but calls on Ftools primitives
- SAS 5.4.1 recently released with updated CCF files, including post-cooling responses
-  There is a different breakdown of functions compared to CIAO and SAS does not, in general,  support data analysis (e.g., spectral fitting, timing etc). SAS allows the users to reprocess the data themselves to take advantage of  the latest algorithms and calibration files**.**

## XMM-Newton -Archive Status

- The ESA developed and supported archive opened on 15 April 	2002. It  is based on the ISO Java archive and has 	reasonable functionality, improvements continue
- The US HEASARC archive server points to both to local 	copies of public data (much faster) and to the ESA 	archive via BROWSE.  European data are accessed in a 	fashion similar to the way Chandra data can be 	accessed.
- Archive hardware will be improved and expanded
- Over 50 GB Downloaded from HEASARC in the last year 	(ftp and http, more via Browse)
- There will be a major reprocessing of all previous observations  	in the next year by ESA, and the archive will contain 	these data
- Reprocessed data will be incorporated into the   	HEASARC archive system.
- Currently 1329 public data sets (2-3/day), 265.1 Gb total

## XMM-Newton – GOF Functions

- ESA support for the GOs and general science
-         community is very limited and ESA has looked to
-         NASA and the the US GOF to support US GOs
- US GOF has had **3 scientists**, 1 system manager, 2
-         programmer and 1 data aid, soon to be **1.5 scientists**,
-         1 system manager, 1.25 programmers, and 1 data aid
- Each scientist has concentrates on one of the 3 XMM
-         instruments but all are fully capable of GO
-         support
- Each gets 25% time for science
- Have funds to hire a new scientist

## XMM-Newton – GOF Functions

-  GOF functions include
-  User support + help desk- primarily through electronic
-         means but there are some visitors, SAS Workshop
-  SAS testing (we are a major  test site)
-  XMM calibration activities – EPIC background 	analysis
-  SAS development
-  New (Ftools based) software, +release and maintenance
-         of instrument team software.
-  Proposal support and proposal support software
-         (ABC Guide, QuickSim,PIMMS, and OM software),
-         development of RPS for XMM for the next AO-3
-  US budget reviews
-  US archive
