RAVE status report
RAVE status report Matthias Steinmetz (AIP) Data collection 11 June 2009 2009 RAVE collaboration meeting Padova 325k spectra for 280k stars (Jan 09) (see Fred‘s talk) Data reduction up to date (March 09) (see Mary‘s talk) 2 11 June 2009 2009 RAVE collaboration meeting Padova Data collection 3 Data collection spectra sp/night avail. fib. sp/n/fib 11 June 2009 nights sched. 05 148 50 4 0 94 38,416 409 92 4.45 06 307 92 4 5 206 96,948 470 107 4.39 07 309 111 38 15 145 65,607 452 98 4.61 08 309 105 21 5 178 64,946 365 83 4.40 wea sys RAV . .

First draft to be discussed in September Terms similar to existing MoU More specific on performance goals RAVE intent: continue operation toward 1M spectra (mid 2012?) 9 Status of UKST hardware 11 June 2009 2009 RAVE collaboration meeting Padova 6 weeks loss of operation in 2007 owing to asbestos removal Poor availability of fibres for 2005-2008 (average ~100 fibres), in particular in 2008 Fibre quality deteriorating FP2 now beyond repair Successful FP3 commissioning in Mar 09 FP1 refurbished to 100 fibres FP2 under remodelling, new fibre bundle FP1 remodelling after FP2 rework is completed 3 fully equipped FP by 2010 10 RAVE finances Currently RAVE operation is secured to mid 2010 11 June 2009 2009 RAVE collaboration meeting Padova We would need about 600k€ to continue until mid 2012 Model: 50% from collab, 50% new partners Discussion with potential new partners Basic model: access for 1 faculty + 1 postdoc + grad students = entrance fee of 100k€ Martin Asplund Tim Beers ANU We need some cash!!! 11 RAVE acknowledgement 11 June 2009 2009 RAVE collaboration meeting Padova Funding for RAVE has been provided by: the AngloAustralian Observatory; the Astrophysical Institute Potsdam; the Australian National University; the Australian Research Council; the French National Research Agency; the German Research foundation; the Istituto Nazionale di Astrofisica at Padova; the Johns Hopkins University; the W.M.
