scaler[28] – [31] contains the sums of all detector counts in fw and bw generated by an FC103 ‘OR’ unit. This avoids counting of double hits.
sb_pos = scaler[28]; sb_neg = scaler[29]; sf_pos = scaler[30]; sf_neg = scaler[31];
The resulting asymmetry and error are written in reserve[0] – [3] for pos. and neg. electric field applied (asy_pos, errasy_pos, asy_neg, errasy_neg). (Only negative polarity if no electric field clock signal present!).
