Changeset 17878 for trunk/Mars

Timestamp:

05/21/14 18:03:56 (11 years ago)

Author:

Message:

Commented the light pulser extraction and the time marker extraction; added saturation treatment; added digital filter; replaced spline extraction by a simplified maximum/half-height-leading-edge extraction; adapted the way how the calibration constant is calculated accordingly
