Wind Tunnel Data Format

Data from the wind tunnel is stored in text format. Each line of the text file constitutes one fifth of a second (0.2 s) of data. For example:

104,2005,109,1132,17,209.07,0,154.44

where the numbers represent the following format:

aaa,yyyy,ddd,hhmm,ss,Young,Davis,Gill

yyyy: year of measurements
ddd: day of the year
hhmm: hour and minute of the da
ss: second of the minute
Young: Young output (millivolts)
Davis: Davis output (number of revolutions per second)
Gill: Gill output (millivolts)

It should be possible to import these data directly into either SPSS or Excel.
