Iceland Mission - #3 [06/01/96] Sean Warren's Data Log Slicer Mission included: Barry Coyle, Jim Garvin, and David Rabine Note: Until Barry Coyle arrived in Iceland to re-align the laser transmitter, all measurements were taken with the beam being bounced off the tube in some fashion so that it was still in alignment, but the beam size and shape would be unknownable. All measurements between 05/10/96 and 05/27/96 are suspect. 05/27/96 and beyond was great. Also Note: When not stated, you can assume that the system being run had the following elements: 80Hz, 1slick80.exe, divergent lens, no scanning *******06/01/96************ Iceland Mission #3 NOTE: Because of cutting through clouds most of the day, some of the return levels will be a little high. This is due to the attenuation I was getting from the clouds would come and go and I could not react fast enough to keep the levels ideal. 2,965,800 [96060101.idl] Data On - climbing to altitude, above 10,000 ft 3,011,920 Data Off 3,012,000 [96060102.idl] Data On - 1st Ice Cap Run 3,038,800 lost signal, going to lower a bit to re-acquire 3,061,166 start of ice data, semi-high altitude 3,081,758 RE-CAL 3,105,470 End of line #1 3,107,550 Data Off 3,107,600 [96060103.idl] Data On - 2nd Ice Cap Run on ice sheets 3,117,412?
