Correlations between binary modules and binary modules - telescope planes are booked in the dspSetup file, which also contains the list of dsp's that are readout and the corresponding detector modules connected to them.

To specify correlations the three key words anchor:, corr: and tele: are used. All of them can be used more than ones.

Key Word Description

anchor: <detector name>
The module <detector name> is an anchor plane and correlations between this module and all other detector modules are created. If N modules are readout (as described in the dspSetUp file), N - 1 correlations are booked.
corr: <first module name> <second module name>
A correlation histogram between the module <first module name> and the module <second module name> are booked and filled.
tele: <binary module name> <telescope plane>
A correlation between the binary module >binary module name> and a telescope plane <telescope plane> is created. The name format for the telescope planes is the following:
tN.x for x-planes
tN.y for y-planes
where N is the plane number (0 - 3).


Histogram id's for binary modules are incremented every time a new correlation is booked. There are three histograms booked: one for the correlation between two modules and two for the difference of the strip numbers. If N is the index for the correlations (N = 0 ... N_max - 1, where N_max is the total number of correlations), the following histograms are created for every correlation found in the dspSetUp file.

13200 + N
two dimensional histogram of the correlation between the two planes.
13250 + N
difference between the strip numbers of the two planes
13300 + N
as 13250 + N, but the offsets from the geometry file are subtracted for both modules.

The correlations between binary modules and telescope planes are booked with the
id's = 13400 + N (N = 0 ... n_max_tele -1), here n_max_tele is the total number of binary-telescope correlations.


The following example reads out five binary modules. Ten correlations between the binary modules them self are booked and three correlations between binary modules and telescope planes.

correlation plots with all the other 4 modules. The histogram id's are from 13200 - 13203.
anchor: lbic2_0
correlation plots of ucsc2 with all the other 4 modules. The histogram id's are from 13204 - 13207. There are now two correlations between ucsc2 and lbic2_0, form the first key (anchor: ucsc2) and this key (anchor: lbic2_0), sorry.
corr: sheff1 lbic2_0
correlation between sheff1 (x-axis) and lbic2_0. Hist id 13208.
corr: sheff1 att7
correlation between sheff1 (x-axis) and att7. Hist id 13209.
tele: ucsc2 t1.x
correlation between ucsc2 and telescope plane 1, x-strips. Hist id 13400.
tele: ucsc2 t2.y
correlation between ucsc2 and telescope plane 2, y-strips. Hist id 13401.
tele: ucsc2 t1.x
correlation between lbic2_1 and telescope plane 0, x-strips. Hist id 13402.
