This CD contains raw data for the Bulion Fault line of the Hector Mine
laser survey performed on April 19th, 2000

Airborne GPS Data: Provided in RINEX format

Raw Laser Data: All files have been zipped using Winzip 7.0

The numbers assigned to the zip files are the numbering scheme used by
the Topeye data collection system, and should just be used for reference
back to the original raw data files.  Basically, each time the LRF is
switched on a new numbered file is produced.

When unzipped, each file is in ASCII format

Tid - Time since UTC midnight in seconds
Lat, Long, Height - aircraft position (WGS84, ellipsoidal elevation)
Pitch, Roll, T_Hdng - aircraft attitude
LRF - raw laser range
PMA - pitch mirror adjustment
SMA - scanning mirror adjustment
NadirA - laser nadir angle
Vertical - vertical component of laser range
Geo X, Geo Y, Geo Z - WGS84 cartesian coordinates of laser target
