Detailed Description

below)

Search for strip with ADC output exceeding theThresholdForAPeak. For each of these strips, build a cluster of strip of size theClusterSize (typically 5 strips). Finally, make a Strip Hit out of these clusters by finding the center-of-mass position of the hit The DetId, strip hit position, and peaking time are stored in a CSCStripHit collection.

Be careful with the ME_1/a chambers: the 48 strips are ganged into 16 channels, Each channel contains signals from three strips, each separated by 16 strips from the next.
