S ALL OR PART OF TIME PERIOD 10 35 0 TO 12 10 50 DESCRIPTION OF RECORD -- 63 PARAMETERS WERE SAVE
D AT THEIR RESPECTIVE RATES. THIS REPRESENTS 585 SAMPLES/PROGRAM CYCLE WHERE A CYCLE IS 1.000 SEC
THE 2 CYCLES OF 585 SAMP/CYC = 1170 WERE THEN SCALED INTO 20 BIT INTEGERS AND PACKED 3 SAMPLES/WOR
D INTO 390 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
T JUSTIFYING 20 BITS AT A TIME AND REVERSING THE ABOVE SCALING PROCESS. AS EXAMPLE, S(I)=N/P(I)-AD(I
