0020 Because the polarimeter data are a mixture of all kind of data,
0021 the only supported interface is the
0022 \begin{verbatim}
0023  packet->rValue(i,"WHAT")
0024 \end{verbatim}
0025 call, which returns a float value (most of the parameters are delivered as floats
0026 from RHIC).
0027
0028 As a rule of thumb, if a field is just a single value, such as "avgAsymXS", then
0029 the "i" parameter is ignored, so just p->rValue(0,"avgAsymXS") will do.
0030
0031 For the arrays, such as "encoderPositionS" (array of 2)  or "bunchAsymXS" (array of 360),
0032 the index has to be in the right range, 0 or 1, or 0<= i < 360, respectively.
0033
0034 If an array is out of bounds, or the keyword is not recognized, the call returns 0.
0035
0036 Here are the keywords, which are just the (somewhat cryptic at times) names of the
0037 fields assigned by CA:
