I guess that since it is some sort of CSV file it displays it as text. Indeed it is the particle counter in the ATF lab.
I believe this is data from the particle counter that has been on the gyro table. Alastair offered to upload it to the elog for me since I had several things to do this afternoon, and Frank needed to use ASUS(?) for a while.
I deleted Alastair's 8000 line elog spam and have attached it here as a zip file. Its called 'DataForAir.gz', but I'm not really sure what this data is from (i.e. what kind of sensor, what location, etc.)
