Minutes of MINIS telecon, 4/28/05

Immediate data analysis projects were agreed on as follows:

X-ray detector gain calibration -- McCarthy
  Product will allow a full gain solution including nonlinearities
   (to first order) based on 511 keV line centroid (for Southern
   flights) and this or temperature (for Northern flights); and
   a standard fitting procedure for the 511 keV line.

X-ray detector instrument response -- Sample
  Product will be a GEANT-generated response matrix for a nominal
    set of energy bins; and a rebinning algorithm to take a 
    spectrum with its own energy channel boundaries (from McCarthy)
    and rebin it to match the response matrix

X-ray detector background model -- Dartmouth
  Does not need to be a tool which gives a complete background for
    any moment -- will probably be constructed on an event-by-event
    basis, either by times nearby or adaptation of data taken on 
    different days.

Electric field instrument -- Houston, UW 
  Bering, Holzworth, Kokorowski and Reddell will work out assignment
    of specific subtasks.  Bering has already posted results of a
    "block despin" at 
    http://gc.phys.uh.edu/data/Other_UH_Experiments/MINIS/
    More advanced tasks for later on include pointwise despin,
       conductivity, power spectra
    
DC magnetic field -- Pulupa
  Sample is looking into purchasing another unit for thermal
    calibrations; Pulupa should look into adapting Gar's IDL
    despin code to the magnetometer, for starters.

**************************************************************

Second-level (science vs. data deconvolution) tasks:

SAMPEX/MINIS comparisons, including theoretical modeling of
 drift dispersion (Sample, Millan, O'Brien, Blake....?)

Full spectral inversions of gamma-ray data

Etc...this list is very incomplete as we didn't have time to
get into it in detail.

Upcoming meetings:
  Spring AGU: Poster is Tuesday afternoon, talk is Wednesday 
    morning (darn).  Bering, Sample,and Smith to discuss specific
    content of both.  Anyone with nice plots, please send them
    to one or all of us. 

    Sample and Millan will work on new versions of composite 
        lightcurves.

    Bering, Sample, and Millan will identify canonical time
        intervals for studying the event seen on 3 balloons.
        Sample and McCarthy will identify a canonical time
            for a solar proton spectrum.  
    These two will be the focus of the early papers.

  AOGS: Smith will present for Sample, based on AGU material.

  IAGA: Gar will be presenting a poster (probably) at IAGA.
        Please send him anything nice that you have to show
        (and copy to David too for the website).

  GEM: (?) Not discussed, but Sample will be there, presumably
       others as well.  What preparations need to be done?

Websites:
  Gar will continue to post his code and plots on the site above;
    Anyone else who would like to post material, please send it
    to me to post at http://sprg.ssl.berkeley.edu/~dsmith/minis/
