Notes
-----
0) KRSP_NWIN holds the total number of in-time discriminator
firings using non-walk corrected times and without a
software charge threshold. KRSP_NWIN_PT uses walk-corrected
times and applies the charge threshold.
1) KRSP_NWIN2 holds the total number of in-time discriminator
firings for a Monte-Carlo event which can be used to study
multi-photon effects.
2) KRSP_NEFF is defined as NWIN - NDARK.
3) KRSP_NCOR is defined as KRSP_NEFF x (1./optical_response) x
(total no. tubes)/(no. tubes online).
4) KRSP_NCORMC is a scaled version of KRSP_NCOR.
This should only be used for testing.
5) KRSP_NEFFICIENT is currently only a placeholder. The total number
of tubes online are counted by several methods:
KRSP_NWORKING : Number of working tubes, tubes which are determined
to be on-line from the DQXX info, the ECA validation,
and the RSPS validation. This number of tubes
are counted towards RSP_NWIN, the primary energy
estimator.
KRSP_NONLINE : Number of tubes defined as 'online' with the DQXX info.
KRSP_NCAL : Number of tubes which are 'online' and pass the RSPS
validation.
6) With the current +/- 10 nsec time window, corrections for
Fresnel transmission through the acrylic interfaces are not
included in the optical response, since reflected/transmitted
light will both be in-time.
7) The raw hit totals for a given event are defined as follows:
a) Number of hits in a prompt time window:
KRSP_NWIN : number of tubes which have fired, are defined as
'working' above, and are in the prompt window,
without PCA walk correction or charge cut.
KRSP_NWIN2: same as above but mulitple hits on the same channel are
counted (MC).
KRSP_NWIN_PT: same as Nwin but using PCA walk-corrected times and
applying a software charge threshold.
KRSP_NWIN_ALLQ: same as KRSP_NWIN_PT but without the sofware treshold.
b) No time window:
KRSP_NHITS: same as KRSP_NWIN_PT but without a prompt time window applied.
KRSP_NHITS_ALLQ: same as above but without a software charge threshold.
KRSP_NHITS_DQXX: number of tubes which have fired and are defined
as 'online' in the DQXX info.
The energy estimator used in RSP is KRSP_NWIN.
8 If calculating both RSP energy types this word is filled with the
alternate energy. Which energy this is depends upon TRSP word 23.
