XMMNewton GOF Overview

1
XMM-Newton GOFOverview

• 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 gt 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 gt 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 (gt 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.

5
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 b 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
