S ALL OR PART OF TIME PERIOD 13 35 40 TO 15 33 0 DESCRIPTION OF RECORD -- 62 PARAMETERS WERE SAVE
D AT THEIR RESPECTIVE RATES. THIS REPRESENTS 62 SAMPLES/PROGRAM CYCLE WHERE A CYCLE IS 1.000 SEC
THE 24 CYCLES OF 62 SAMP/CYC = 1488 WERE THEN SCALED INTO 20 BIT INTEGERS AND PACKED 3 SAMPLES/WOR
D INTO 496 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
), WHERE N IS THE 20 BIT SCALED INTEGER, S(I) THE DESIRED UNSCALED PARAMETER, AD(I),P(I) THE CORRESP
