FA125 firmware check
Contents
Used the raw samples to emulated the fa125's calculated values and compared them with the fa125 output.

Many of the problems in 3923 were due to hardware faults in roc28 slots 5&6.
11770 of the 12798 difference in integral were due to faulty assignment of the overflow bit. This has been fixed.
There were a few problems in the firmware which Cody described & fixed before run 4062. The remaining issues are not critical.
Differences in data/emulation from run 4062
The first 4 are firmware logic, & not necessarily a mistake (could be a mistake in the emulator); the remaining 3 are more weird.
1. Integral differences - these are from very late hits where there is a small peak at the end of the hit search window that only just clears the threshold crossing, followed by a larger peak a few samples later. The timing algorithm returns the time for the larger peak and the emulated integral is 0 because it is out of the window. [Cody to fix]
2. Amplitude differences - both firmware and emulation are starting the peak search from the threshold crossing sample but it should really start from the sample containing the leading edge time, since very occasionally the search will pick up a different peak (usually a small one before a larger one). [Cody and Naomi to fix]
3. Amplitude differences - early hits - 70 of the 98 differences are where the samples at the start of the window are over threshold, decrease for one sample and then rise again, ie. hitsample==20 && (adc[20]>=adc[21]) && (adc[21]<adc[22]) where adc[20] is the first sample in the hit search window. Emulator returns maxamp = adc[20]; firmware returns amp of the following peak. [Cody to fix]
4. Amplitude differences - later hits - 28 of the 98 differences seem to have no apparent cause, no association with roc/slot/channel, in most cases the max amp reported is larger than all the sample values [???]
5. Overflow count - the firmware is counting overflows from the hit sample - PG on, but the emulator counts them for the entire data window. Naomi will change the emulator to match the firmware. [Naomi to fix]
6. Missing pulse or WRD - pulse & Window raw data are separate objects in the evio eventloop, not linked yet. One out of sync pair causes the rest of the data for that trigger to be out of step.
[from WRD without straws, all digihits have straws, David to fix w association]
fa125 object mismatches - consequence of missing pulse data
Every now and then a CDCPulseData is missing from the start of an event and then the following subsequent CDCPulseData and WindowRawData objects are out of step for a while (the mismatches continue into following events and eventually stop). The objects are kept together in the analysis code when the PulseData is associated with the WindowRawData.
In run 4731 Beni found 2 pulse data words missing from 57 files
Insufficient samples
eg eventnum 6520553 and 6520556 in Run003923. Naomi finds insufficient samples, Beni does not.
