The 16 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. Data file is formatted as 16I6. Note that the number which appeaars in column 1 may not be channel 0 (because record may be out of sync.) Example : the address bit of number 7770 indicates it is channel 1, hence it is Volt. reference. (7770= 0001 1110 0101 1010) (on vax bit 12-15 of 7770 is 0001) Cal file information: Cal header file is created from Ron Perkin PC Ctd 25 lines header.
