Annual Review

15 March 04

slide3
Purpose of the Review

Present to ESA/ESO management

Staffing and cost overview

Plans for 2004

Major action item: ECF transition plan

HST >> JWST

Cancellation of SM4

Archive/Virtual Observatory

ESO-ESA Coordination

Outside advisors to represent users/community

slide4

ST-ECF Overview

Rudolf Albrecht

The Hubble Space Telescope (HST) is a joint project between the US National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA).

The Space Telescope European Coordinating Facility (ST-ECF), jointly operated by ESA and the European Southern Observatory (ESO), is the European HST science facility, supporting the European astronomy community in exploiting the research opportunities provided by the Hubble Space Telescope.

slide5
STECF Overview

Tasks

Support of the European HST users

Information: Newsletter, Web Site

Data analysis : SCISOFT, special processing,

beta test site

Proposal support: APT s/w mirror, etc.

TAC process

One-on-one support for European researchers

slide6
STECF Overview (cont’d)

Carries out some of the tasks defined in the MOU (“Letter of Agreement”) on HST between NASA and ESA

Archive access for European community

data distribution, added value products, VO compliance

HST SciInst calibration enhancement / final processing

Significant enhancement of the science value

European HST outreach

Major increase of the visibility of HST/ESA/ESO

slide7

STECF Overview (cont’d)

  • Supports the HST project through collaborations with STScI
    • ACS and NICMOS spectral mode, UDF spectral processing
  • Supports ESA activities
    • JWST, VO, Opticon
  • Supports ESO activities
    • VO, Office for Science, Faculty, Instruments, Science
  • Acts as an interface/coordinator between ESA and ESO
slide8
STECF Overview (cont’d)

Staff:

5 ESA (3 indef) 1 ESA on leave

7 ESO (5 ISM (3 indef); 1 PA)

7 ESO charged to ESA

1 “subcontracted”

1 Archive operator

3 Calibration

2 Outreach (1PA)

1 ESO funded by EC/VO

1 contractor (sys admin)

One person seconded to ScI- works extremely well

Turnover: 4 (5) departures, 4 arrivals

slide12
HST status

Telescope alive and well

Business as usual for the time being

Cancellation of SM4

Collect user input

Participate in the brainstorming effort

Get ready to process 2-gyro data

ECF has very powerful image restoration s/w developed to cope with the HST Spherical Aberration problem

slide13
HST status: concerns

FGS3: original unit, load needs to be limited

FGS2R: thermal stability concerns

Batteries: optimize charging and reconditioning procedures

Gyros: most serious current concern

Thermal: hot limits reached, work-arounds

Communication: in good shape, but..

SI’s: ACS, WFC2, NCS all right; STIS lost side one, shows CTE problem.

slide14
Cycle 13 Call for Proposals

Phase I submitted 23 Jan 04

949 proposals, 170 European

Panels meet 22-24 March

TAC meets 25-27 March

20+ Europeans involved

PI notifications: 04 April 04

slide15

ESO/ST-ECF Science Data Archive

Rudolf Albrecht / Alberto Micol

slide16

HST and ESO Archives are fully integrated

    • Common H/W and S/W, joint planning
  • The ECF HST Archive receives all HST data in near real time
  • Only raw data are archived to minimize bulk media expenses
  • Successful cooperation with STScI and CADC
    • Regular Archive Coordination Meetings
    • Data & Metadata Distribution (from/to STScI and CADC)
    • On-The-Fly Recalibration (telemetry -> calibrated products)
    • Value added products (development and maintenance)
    • AOB (data releases, etc.)
slide17

Archive Operations (current status)

Total holdings: ESO 19,750 GB, HST 1,800GB

Year  Ingested  Requests  Distributed(GB) Users(off-site)

2002    640 GB      1630         520 GB    240

2003    475 GB      1940        2400 GB    287

2004* 365 GB 2880 3700 GB 550

* 2004 is a projection based on the first 2 months (without UDF)

Data delivery on DVDs, Network, and USB disks (starting April)

Total ECF staff: 3.75 FTEs (1.25 operations, 2.5 development)

slide18

Successful cooperation with STScI and CADC (1/4)

  • Data & Metadata Distribution (from/to STScI and CADC)
    • Every day we exchange:
      • Telemetry, Jitter, Calibration Reference Files
      • A number of Databases (headers, calibration DB, etc.)
      • Preview Images & Spectra (from CADC)
      • WFPC2 (and ACS in dev.) Association database
    • Maintenance and integrity checks (mostly automated) daily required
slide19

Successful cooperation with STScI and CADC (2/4)

  • On-The-Fly Recalibration (telemetry -> calibrated products)
    • After initial headaches, smooth operations have been achieved
    • About 4 new software releases/year
    • ST-ECF installs OTFR s/w both at ESO and at CADC
slide20

Successful cooperation with STScI and CADC (3/4)

  • Value added products (development and maintenance)
    • WFPC2 and ACS (in development) associations and enhanced products (deeper, better astrometry and photometry)
    • Enhanced recalibration (POA) of the entire FOS archive
slide21

Successful cooperation with STScI and CADC (4/4)

  • AOB
    • Mirroring the APT (Proposal Preparation) tool
    • Joint release/mirror of the GOODS data (Oct 2nd)
    • Joint release/mirror of the UDF data (March 9th)
  • March 9-10, 2004
slide22

Towards the Virtual Observatory

  • Migrating the HST archive to the VO level requires
  • efforts in the area of:
  • Contents (Data Quality)
    • On The Fly Recalibration + Preview done
    • WFPC2 & ACS association-enhanced products on-going
    • Enhanced calibration/final processing done/on-going
  • Data Description (Enhanced metadata)
    • WFPC2 & ACS associations, plus image content descriptors (“sextracted” catalogue parameters, e.g., num of stars/galaxies, etc.) on-going
  • Interfaces
    • Querator (improved scientific interface, astrovirtel) Oct ’03
    • Adoption of VO standards to ensure interoperability on-going
  • Resources
    • ESO/ESA resource mismatch coming up
slide23

ASTROVIRTEL (EC-funded)

  • EC-funded 3-year project, designed to identify VO science requirements. Terminated Dec 2003, final report submitted Feb 04
  • Summary
    • 3 Calls for proposals, total of 31 proposals received
    • “electronic” peer review accepted 14 proposals
    • 36 users produced 25 papers (to date)
    • A student at ESO produced a PhD thesis
    • The ASTROVIRTEL S/W person got a job at NOAO
  • Lessons learned
    • We learned how to write proposals for EC funded programs
    • The project was audited by the EC. Satisfactory results.
    • Significant administrative overhead
