As final data is calibrated after raw data has been edited, the parameters actually used for calibrating raw data have been lost. (Dec., 1987) The 16 raw data channels are numbered from 0 to 15 : Blank, Volt. reference, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., Cond. offset, Bottle Trip Flag, Touch Down Flag, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., and Cond. offset. Raw data file is formatted as 16I6. Note that the number which appears in column 1 may not be channel 0 (because record may be out of sync.) There are 4 bits in each number to represent which channel that the number shall be in (Vax : bit 12-15, Sperry: bit 21-24). Example : the address bit of number 7770 indicates it is channel 1, hence it is Volt. reference. (7770= 0001 1110 0101 1010) (on the VAX, bit 12-15 of 7770 is 0001) *ADMINISTRATION MISSION : 1981-74 AGENCY : IOS, Frozen Sea Research Group, Sidney, B.C.
