@@ -64,4 +64,3 @@ The sorting code requires a calibration/configuration file.
 This file describes the data acquisition system, the number of detectors, what detector are connected to what DAQ channel, and the calibration of the detectors.
 Examples of these files are `cal/LaBr250MHz.yaml` for OSCAR configured with 250 MHz XIA modules for LaBr$_3$:Ce, while the E detector was read out with a $500$ MHz module.
 The file `cal/LaBr500MHz.yaml` is for a OSCAR setup where the LaBr$_3$:Ce detectors are read out with 500 MHz modules and all Si detectors with 250 MHz modules.
