These times are different from canister valve actuation times in the first data submission (3/21/96) and should correct for manifold delay times. Calibrations for these compounds is ongoing. Measurements of other compounds may be available, please inquire. 0.0 - Concentration Below Detection Limit Preliminary Data Initial screening identified some data points which were removed in the current file until verified by reanalysis. An appropriate procedure for averaging high frequency data into WAS fill time is developed and integrated files for different parameters have been produced. Please contact if interested. Flag column: A value of 1 means no flag was put on the preliminary data.
