On November 16,2000 we pressurized the ATIC
vessel to 4 psi relative pressure and then monitored the internal
temperature and pressure for several days to determine the pressure
vessel leak rate. The data is in a text file with three columns:
relative time in seconds from the start of the test, the temperature in
Kelvin and the absolute pressure in pounds per square inch. The start
time of the test was 11/16/00 11:11:57 am.
