S ALL OR PART OF TIME PERIOD 18 30 15 TO 19 37 0 DESCRIPTION OF RECORD -- 63 PARAMETERS WERE SAVE
D AT THEIR RESPECTIVE RATES. THIS REPRESENTS 63 SAMPLES/PROGRAM CYCLE WHERE A CYCLE IS 1.000 SEC
THE 23 CYCLES OF 63 SAMP/CYC = 1449 WERE THEN SCALED INTO 20 BIT INTEGERS AND PACKED 3 SAMPLES/WOR
D INTO 483 60 BIT PACKED WORDS --METHOD OF SCALING-- A BIAS AD(I) WAS ADDED TO EACH SAMPLE
OF EACH PARAMETER TO ELIMINATE ANY NEGATIVE VALUES. THE BIASED SAMPLE WAS THEN MULTIPLIED BY P(I)
TO INSURE THE PROPER NUMBER OF DECIMAL PLACES WERE SAVED. THE PACKED RECORD MAY BE UNPACKED BY RIGH
