ROLL.TXT: ROLL ANGLE ANCILLARY DATA FILE This file contains roll angle estimates history as derived from SIR-C null tracking algorithms developed by J. C. Curlander, et al. GMT is expressed as (YYYY/ddd:hh:mm:ss.s). Roll angles are expressed in degrees. 1 2 3 4 5 6 7 1234567890123456789012345678901234567890123456789012345678901234567890123456 Data Take ID: 156.20 Site Name: Siwa/Largeau, Sahara Chad Site ID: GS7
