EFFECTIVITY CORRECTION - HED 3X HIT LEVELS
Format(s): f10
ERNE Effectivity Coefficients for HED 3x Hit Levels
Version 1.0 (TM format f10)
Usage: multiply lev-3 intensity values for measurement periods with HED 3x
hit levels by the tabulated numbers below.
Version history:
1.2 - 2003-01-29
New values based on f10 measurements during 1996.
Two 1x/3x hit level period pairs were considered:
2.6 - 17.6 1x
19.6 - 31.7 3x
1.11 - 1.12 3x
3.12 - 19.12 1x
Results:
1) The LED channels and lower HED channels had higher
average intensities during 3x-hit level periods
resulting in correction factors smaller than 1.0.
This was presumably due to small particle events
that were present during the (longer) 3x integration
times.
2) HED channel 11 was empty as anticipated.
3) It seems that only HED channels 6-10 were affected
by the hit level changes. This conforms also with the
earlier understanding. The corresponding correction
factors between the two periods are also in good
agreement. This is in contrast to other energies,
where the differences tend to be much bigger. This
seems to indicate also that the small particle events
had no effect in the higher HED energies.
The correction factors for the HED channels 6-10 in the
table are set to average values attained from the two
periods. Other factors are set to 1.0.
1.1 - 2002-06-18
New values based on format-40 values (hedx3eff.4.0)
The f10 coefficients are calculated from the f40 proton
values by weighting the f40 coefficients with the
GdE-values of the contributing f40 energy channels.
In other words, these values are weighted sums of
the f40 values, weight factor being the corresponding
GdE-values.
