Cosmic rays were used to measure drift chamber time spectra with respect to scintillators placed above and below the drift chambers (more details are at the wiki location CLAS12R1_CosmicTestStand)
Below are the hits abserved for 16 sense wires. Wire 54 is plugged into a bad discriminator channel.
Cosmic measurements
