TABLE of polynomial coefficients Ci, for channel 01 of the
SDC instrument at 4 temperatures, fitting the response
relationship
log10( Q(DN) )= C0 + C1 x DN + C2 x DN^2 + ... + C18 x DN^18
where Q is an input charge to the SDC instrument channel, in units of
'Number of equivalent electrons,' and DN (Data Number) is the 16-bit
digital output that results from input Q.
The values in this TABLE apply to one SDC channel (01), and each
COLUMN corresponds to one temperature.
The first ROW contains coefficients C0, and the last ROW contains
coefficients C18. There are typically fewer non-zero
coefficients than ROWs in the TABLE.
This TABLE is one of several archiving calibration parameters used in the
calibration of SDC data.
Details of the calibration may be found in the SOC ICD document,
which was delivered with this data set.
Genesis of the calibration data (from the ICD):
In a temperature controlled environment, the electronics from the end of the
PVDF to the DN in the raw data were calibrated, at each of 4 calibration box
temperatures and for each of the 14 channels. This was done by injecting 19
(actually 21; see the ICD) fixed-amplitude charge pulses 100 times into a
channel and recording the DN value each time. From those recorded values,
the average DN (DNavg) and its standard deviation (SIG) at each charge pulse
amplitude, box temperature and channel were calculated. Then, for each box
temperature and channel, a 9th order polynomial fit of Q(DNavg) was derived.
Finally, these 3 sets of values (the polynomial coefficients, DNavg, and
SIG) were stored in a matrix. This matrix contains all information required
to calculate the charge equivalent to a DN as a function of box temperature
and channel (detector), as well as the uncertainty in that calculated charge
value.
That matrix has been broken out into forty-two PDS ASCII TABLEs; this TABLE
is one of those forty-two.
