What is the correspondence between the PROS 34-channel spectrum and PI bins?

(8/22/91)


The correspondence between the 34-channel spectrum and PI bins is listed below.

As per a note from G. Hasinger et al. of 8 July 1991, the first output channel will be zero, as it is corrupted in converting from PHA to PI bins.
