ESPACE Internal Variables

All of internal variables used for shower detector software programming into ESPACE, are formed in form of structure. This structure, named /shower/ was inserted into FORTRAN include file espace_type.h.

In the following tables for every used variables (in the first column) it fortran type (in the second column), program module name where variable is set (the third column) and brief description of variable (in the fourth column) are are shown.

In the table the following designations are used:

• spdetector.sp(1).trigger.sh(ish) (or spdet.trigger.sh(ish), etc.) precedes to a variable name in the first column, where spdetector is a record of structure /allspectrodet/ (spdet is a record of structure /onespectrodet/), ish=1 for Preshower and ish=2 for Shower.
• In the variable type column I means an integer type, D -- real*8 type, and L -- logical type.
• Index $i$ shows detector block number and has values $i=1\; ÷48$ for Preshower and $i=1\; ÷96$ for Shower.
• Index $n$ points to the fired blocks of detector and has values $n=1\; ÷$ spdetector.sp(1).trigger.sh(ish).nblock.adc.
• Index $j$ shows number of hit on detector and has values $j=1\; ÷$ spdetector.sp(1).trigger.sh(ish).nhits.adc.
• Index $k$ shows cluster number, reconstructed in detector, and has values $k=1\; ÷$ spdetector.sp(1).trigger.sh(ish).ncluster.
• Index $l$ points to blocks of reconstructed clusters and has values $l=1\; ÷$ spdetector.sp(1).trigger.sh(ish).clust(k).mult.

 

Variable T Where is set Description

hitbit I user_init Hitbit assigned to the detector.

adc_range I user_init Maximal value of range of ADC amplitudes.

geom.p.x D read_geometry X-coordinate of the detector center.

geom.p.y D read_geometry Y-coordinate of the detector center.

geom.p.z D read_geometry Z-coordinate of the detector center.

geom.nblock I read_geometry Number of detector blocks.

geom.block(i).p.x D read_geometry X-coordinates of detector blocks centers.

geom.block(i).p.y D read_geometry Y-coordinates of detector blocks centers.

geom.block(i).p.z D read_geometry Z-coordinates of detector blocks centers.

cor(i).offset.adc D shcal_coef_io Mean values of channels Pedestals.

cor(i).amplitude.adc D shcal_coef_io Values of calibration constants.

cor(i).offset_sigma.adc D shcal_coef_io Values of Pedestals $\sigma$.

The following parts of the structure is overwritten for every hit.

Variable T Where is set Description

nblock.adc I read_show_e Number of blocks that fired.

blocks(n).adc I read_show_e Array of block numbers that fired.

nhits.adc I read_show_e Number of hits on detector.

blocknr(j).adc I read_show_e Pointer to block number for each hit.

hitnr(j).adc I read_show_e Pointer to hit number in a block for each hit.

block(i).fired.adc L read_show_e Flag which shows if block was fired.

block(i).nrhit.adc I read_show_e Number of hits on the block.

block(i).val(1).adc I read_show_e ADC values of detector blocks.

block(i).cor_val(1).adc D read_show_e Corrected ADC values of detector blocks.

Next part of the structure is overwritten after the shower clusters reconstruction in the detector.
