We decided to reinstate data type 5 (window raw data) for reading out pedestal data in the absence of a hit, and to use this instead of type 6, pulse raw data. This leaves us with data types 5 (window raw data), 7 (pulse data) and 8 (combined - pulse data followed by raw data). Window raw data would be used for configuration; pulse data would be the usual hit event readout; the combined format would facilitate algorithm development and monitoring.
- David has already updated and redistributed the document.
The integration requirements for the 2 detectors are not identical - the CDC has pulses which can start at any time during a window of nearly 1us but all end at the same time, whereas the FDC pulses can start at any time during a shorter window, and are much shorter in duration. There are benefits to having one firmware package which would be used for both FDC and CDC; this would work best if there could be software settings to specify that (eg) a certain process should be used for the FDC and another for the CDC.
Beni is going to implement Naomi's timing algorithm for the FDC to see how it performs.
