Comments : Comment added on March 14th 2003 16:00. Although the run was mostly
dedicated to bringing the receiver in shape for summer ops there is a chunk of
valid Rayleigh data towards the end of the run. The times are framed below:

04:07:41-06:13:36 Good Rayleigh data
06:18:37-06:30:40 Good Rayeligh data
