IRAM millimeter interferometry center

• IRAM ARC node will be an activity of the IRAM
  millimeter interferometry center
• Center is already in place
• GILDAS software (CLASS, CLIC, )
• PdBI f2f user support since gt10 years
• mm-interferometry school series since 1998
• general expertise in mm-interferometry
  calibration and imaging techniques

ARC node at IRAM

• Goals of mm-interferometry expertise center
• User formation
• User face-to-face support
• Technical expertise center
• Data reduction software
• Based on and fully open to collaborations with
  other groups
• Several actions already started or planned

8
User formation

• Interferometry school series
• ? 5th school Oct. 2-6 2006, 66 participants
• Long-period visits of PhD/postdocs
• Formation to mm-interferometry techniques and
  data reduction, observations at PdBI (new access)
• Can start in 2007 (new building available)
• Please contact us if interested

9

• IRAM mm-interferometry school series
• Every two years since 1998
• General introduction to mm-interferometry, PdBI
  data reduction, introduction to ALMA
• ALMA practical session in 2008 (? Early Science)
• Lectures and book available on the web

10
User f2f support

• In place at IRAM for PdBI since 10 years
• Each project has a local contact to help during
  the data reduction at Grenoble
• Will be extended to support ALMA users
• Critical for early-science ? required in 2009

11
Technical Expertise

• ALMA commissioning
• GILDAS to be used for antenna SD holographies
• New observing mode OTF interferometry
  development at PdBI then ALMA (EU-FP6)
• Using Jupiter satellites as mm flux calibrators
  PdBI/30m project started (collab. with Paris
  Obs.)
• ALMA imaging simulator

12
Software devlt

• Software developments for ALMA
• telescope calibration pipeline
• GILDAS/CLIC adapted for ALMA holographies
• goal long-term support/upgrade of ALMA software
• pyGILDAS development interoperability of the
  data reduction software (collab. with Bordeaux
  Obs.)
