Info here has been gathered from Mike Henderson's c program top produce merged
data files.

All this info has been gathered into two files:

1. cal_cpa_sopa_esp.txt

For all LANL birds the cal info for CPA, SOPA and ESP instruments as best we
know. 

ESP has full 9 channel energy resolution, calibration factors have been
adapted to give same results as the 6- channle info in the merged files.
This is ongoing work, better factors need to be incorporated.

The fcf here are single factor to convert from c/s to diff flux ion keV,
including geomertic factors, efficiencies and energy ranges fro the channels:

Diff Flux = (counts per second) / (G Eff. delta E)

fcf = (G Eff. delta E)   i.e. dived counts/s by fcf's to get diff flux.


2. cal_merged.txt

Same format as the file above but since mreged fiels already are calibrated,
all fcf's are set to one. 


-----------------------------------

old info from Mike below

The file FluxConversionFactors.txt contains all the flux conversion factors
for CPA and SOPA. File EnergyRanges.txt contains the energy range headres from
the 10 sec files.

To convert counts/s -> Flux do the following;


    if  C = counts/s
    and F = flux

    then  F[i] = C[i]/FCF[i]


I.e. you divide the Counts/s by the FCFs contained in the file.
