Stage 2 Create histograms for track angle
correction.
Stage 1 Do distance-to-time (X-T) calibration

• 1. Loop over all events in all
• files in runlist
• 2. Make list of complementary
• pairs of hits
• 3. Use XT calibration histogram
• to convert time to distance.
• 3. Mark the drift sense of the
• hits. drift sense or - 1
• 4. Fill in histogram of SOD versus
• (drift sense)(track angle)
• 5. Do simple analysis of where the
• inefficient hits are in the straw
• 6. Do simple analysis of where the

• 1. Loop over all events in all
• files in runlist
• 2. Fill histograms used for
• inverting the distance-to-time
• relationship. Only works if
• illumination in straw is uniform.

Stage 3 Create histograms for residual in-cell
correction. This correction is very small. It
corrects for non-linearities in the XT
calibration.
