I've done some slight changes (updates, correction of mistakes) to the prespec-tutorial that you can find in the prespec/doc/PreSPEC_Tutorial directory of the package. Some while ago, I also added a FAQ section, describing things like: making logical AND/OR of different conditions and how to define and use gates.

I pushed the following changes in Frs Id processor
- Calculation of AoQ without correcting the Rho included
- A new way to get charged states based on P. Mayet PhD thesis and J. Benlliure, Nucl. Phys A660 87 (1999)
- A parameter to indicate if there is S1 degrader in the settings. This is useful when calculating the BRho of the first half of FRS and charged states

I have pushed a change in the position correction of the musics.
Instead of
dE=dE+x*value/dE
i take
dE=dE-x*value
Where value is the slope of the line one fits to the dE_geo vs position in the musics plot.

There is a new processor for the mutual alignment of correlated signals. It can determine a set of offsets, such that all differences between pairs of signals will be zero.
One possible application of this: Consider the time signals of a LYCCA ToF detector. These signals have an offset with respect to each other, because of slightly different cable length (and maybe other reasons). As a consequence, if a particle hits the detector, Then signal from PMT_a will come not exactly at the same time as the signal from PMT_b, even if both signals were induced by the same particle. This offset is of course the same for each event. The processor CircularMembraneScintillator takes these offsets into account. But in practice, these offsets tend to induce difficulties in the calibration. Therefore, it might make sense to align the time signals before feeding them into the final processing.
processor ToFstart/SignalAlignment UTILS.InterSignalAlignment
INPUT[0:15] <- LyccaTargetTofCrate.mhtdc0[0:15]
INPUT[16:31] <- LyccaTargetTofCrate.mhtdc1[16:31]
display INPUT_DIFFERENCES 10000,-5000,5000
display OUTPUT_DIFFERENCES 10000,-5000,5000
end
# use output of the time alignment instead of the raw data
processor Lycca/ToFStart/Preproc UTILS.MhTdcPreprocessor
input[0:31] <- ToFstart/SignalAlignment.OUTPUT[0:31]
end
The parameter file for the InterSignalAlignment might look like this:
NUM_SIGNALS 32
NUM_BINS 8000
BIN_WIDTH 1
CALIBRATE 1
WRITE_INTERVAL 1000
Where the most important parameter is NUM_SIGNALS (32 PMTs in this case). The other parameters are for tuning the automatic determination of the offsets. Look into the header file for detailed description.
I've tried out a new style of writing the processor code: I wrote every in/output,parameter,etc. in CAPITAL letters. The reasoning behind this: Trying to avoid the common mistake, that one accidentally writes when actually would be correct. The capitals are clearly enums and no normal variables.

I included a new processor to get the ToF from the MhTDCs. Is called TofSystemMhTDCSc and is in the UTILS plugin.
It calculates differences between hits for ToF left and Tof right and takes the first combination which gives ToF inside a window.
Using this hits time left - right for each scintillator is also given

There is a new feature in the config file parser.
It can evaluate integer expressions now.
If it finds curly braces, it will evaluate the expression inside and replace the complete string (including the curly braces) with the result of that expression. It supports common operator priority ('^' binds more than '*' or '/' which bind more than '+' and '-') and parentheses '(' and ')'.
Example:
"{2+2*3}" -> "8"
"{(2+2)*3}" -> "12"
It is in particular meant to be used in for loops, for example:
processor even_channels UTILS.SingleArray
for $i in [0:15]
array[$i] <- AdcCrate.adc[{2*$i}]
end
end
processor odd_channels UTILS.SingleArray
for $i in [0:15]
array[$i] <- AdcCrate.adc[{2*$i+1}]
end
end
