18. Configuration and TOS / TOF versions Appendix
In this appendix we will present the TOS configuration file used for data taking at CAST and shortly note on versions of TOS and TOF used.
18.1. TOS configuration file
Below is the configuration file as it was used at CAST during the data taking periods. Most notably it contains the required address for the FADC in the VME crate, the high voltage settings (groups, voltages and current bounds) and the FADC settings (channel, trigger threshold etc.).

18.2. TOS and TOF versions used at CAST
For the DAQ software TOS unfortunately no discrete git tags exist, due to its rocky development. However, based on the git repository (Schmidt 2022d) and the dates of the start of the data taking campaigns (see 10.1), it is simple to deduce the corresponding commits which were used.
The detector firmware versions, TOF, have an even less well defined
history. No development history exists, strictly speaking. The .bit
files are available, but their names are very 'descriptive' in nature,
but do not contain any version numbers either. If memory serves
correctly, the version used in Run-3 at CAST contained something
like szint1_fixed in its filename, indicating that the scintillator
trigger logic was fixed (which was the major bug in Run-2).
18.2.1. More notes on the TOF versions extended
Tobi expressed some of his development frustrations by coming up with ever more creative ways to name the binary files!
The initial version might have been bastis neues lielibings tof or
something like that. Well, it's not like it matters much at this
point, which is why I did not spend any time really digging into which
version exactly was used.
