  • connection information at bottom of page
     
• Agenda
  
  • short (5 minute) summaries (if necessary) from participants about:
    • contamination status of current instruments
      • Paul - ACIS contamination model verification with E0102
      • Herman - ACIS contamination model update (i.e. rebuttal)
      • Eric - XIS update
      • others?
    • plans for future instruments
      • anyone?
         
  • status of action items
    • A/I for all instruments (due 31 July 2014)
        estimates of C,N,O,F, etc. column densities (multiple epochs are fine)
        estimates of optical depth @ C edge, O edge, 1 keV 
        ACIS: Herman Marshall 
        XMM EPIC MOS: Steve Sembay 
        XMM EPIC pn: Steve Sembay 
        XMM RGS: Michael Smith 
        Suzaku XIS: Eric Miller
        Swift XRT: Andy Beardmore
      
      I think it would be useful to collect this information so I can present it all in one handy plot.  Would it be possible for the individuals listed above to send me those data by April 13?  Measured values on-axis at some representative epoch(s) are most useful; at least the most recent epoch should be included.  If there is measured spatial dependence (e.g. ACIS and XIS), then a single off-axis datapoint, e.g. halfway out to the edge of the FOV, would also be useful.  I will think of some way to combine all of this into one plot, maybe something akin to the E0102 line normalization plot that Paul shows.  We can discuss this more at the telecon.
      
      
  • discussion about how to structure the 1 x 1.75 hour WG sessions at upcoming IACHEC, which could include:
    • one WG session scheduled, 21 April 14:00-18:00 (4 hours)
      • do we need all that time?
      • who has other WG conflicts to work around?
      • Paul suggests defining a 2-hour primary meeting period for each session, with extra time for extra work if people want
    • who will attend the Beijing meeting? can we skype with European contingent (Andy, Steve S.)?
      so far we just have Chandra and Suzaku representatives in attendance
