Calibration runs

Folks,

Yesterday (6/2) we performed a series of calibration runs. The data files
are in /raid/stage_in, which is as of yesterday only accessible from clon00.
Hopefully this will be changed. The files and descriptions are:

clas_fc_tdc_002547.a00 (tdc calibration)
TOF_LAS_002552.a00 (laser run illuminating fibers 1,5,9,...)
TOF_LAS_002553.a00 (laser run illuminating fibers 2,6,10,...)
TOF_LAS_002554.a00 (laser run illuminating fibers 3,7,11,...)
TOF_LAS_002555.a00 (laser run illuminating fibers 4,8,12,...)
TOF_LAS_002556.a00 (laser run with no mask)

Note that these runs masking the fibers does not use the mechnical masking
device built by W&M but a piece of paper covering the fibers. The mechanical
device needs to be aligned properly (we think) for it to work. The
intention behind the mask runs is to check out the translation of the data.
Looking at these runs using the single event display (ced) indicates that the
translation appears to be mostly working properly, with a few
exceptions. Other people may want to confirm this.

Simon.
