The compute_geometry.py file computes both the sensor corner coordinates and centroid coordinates, as well as two orientation files used by the segment linking algorithm, using the compute_corners.py, compute_centroids.py, and compute_orientation.py files respectively. This is the only file that you need to run prior to generating the module maps and pixel maps. Documentation for the individual geometry python files it calls are also given below, but do not need to be run in addition to compute_geometry.
Usage:
Run: python3 compute_geometry.py for default file paths.
For custom paths: python3 compute_geometry.py [module_info_file] [sensor_info_file] [outputfile_corners] [outputfile_centroid] [outputfile_tilted_barrel] [outputfile_endcap]
Default module info file: data/module_info_OT800_IT615.csv
Default sensor info file: data/DetId_sensors_list_OT800_IT615.csv
Default output file for corners: output/sensor_corners.txt
Default output file for centroids: output/sensor_centroids.txt
Default output file for tilted barrel orientations: output/tilted_barrel_orientation.txt
Default output file for endcap orientations: output/endcap_orientation.txt
After running the compute_geometry.py file (see above) the following can be run.
Use the scripts:
python3 compute_pixelmap.py
python3 compute_modulemap.py
This will place the modulemap output to the output/ directory and the pixelmaps to their own pixelmap directory.
After creating the module map and pixel map with the above scripts, you can convert the relevant files stored in output/ to a binary format for use in Tracklooper with the following command:
python3 convert_binary.py
The compute_centroids.py file computes the centroid coordinates of each sensor using the CSV files in /data
Usage:
Run: python3 compute_centroids.py for default file paths.
For custom paths: python3 compute_centroids.py [inputfile] [outputfile]
Default input: data/DetId_sensors_list_OT800_IT615.csv
Default output: output/sensor_centroids.txt
Output Format:
sensor_centroids.txt - [sensor detid], [x coordinate of centroid (cm)], [y coordinate of centorid (cm)], [z coordinate of centroid (cm)], [moduletype (23 (PSP), 24 (PSS), or 25 (TwoS))]
The compute_corners.py file calculates the four corner coordinates of each sensor based on the provided module and sensor CSV files. It uses rotation matrices to account for various rotations of each sensor and outputs the corner coordinates for each sensor.
Usage:
Run: python3 compute_corners.py for default file paths.
For custom paths: python3 compute_corners.py [module_info_file] [sensor_info_file] [outputfile]
Default module info file: data/module_info_OT800_IT615.csv
Default sensor info file: data/DetId_sensors_list_OT800_IT615.csv
Default output file: output/sensor_corners.txt
Output Format:
sensor_corners.txt - "sensor detid": [Z, X, Y coordinates for each of the sensor's four corners (cm)]
The compute_orientation.py script calculates the orientations (dr/dz and dx/dy slopes) of each relevant sensor based on their corner coordinates. It outputs two files: one for the slopes of tilted barrel sensors and another for the slopes of endcap sensors. Note that only the dxdy slope is given for endcap sensors because dz is always 0 in the current geometry for the endcap sensors. Additionally, for endcap sensors, the centroid phi value also appended to orientation information.
Usage:
Run: python3 compute_orientation.py for default file paths.
For custom paths: python3 compute_orientation.py [sensor_corners_file] [centroids_file] [output_tilted_barrel_file] [output_endcap_file]
Default sensor corners file: output/sensor_corners.txt
Default centroids file: data/DetId_sensors_list_OT800_IT615.csv
Default output file for tilted barrel orientations: output/tilted_barrel_orientation.txt
Default output file for endcap orientations: output/endcap_orientation.txt
Output Format:
endcap_orientation.txt - [endcap sensor detid] [dx/dy slope of sensor] [centroid phi value of sensor]
tilted_barrel_orientation.txt - [tilted barrel sensor detid] [dr/dz slope of sensor] [dx/dy slope of sensor]
