The measurements of altitude, pressure, temperature, latitude, longitude are made only once during each 5 minute sample. Thus these values are constant across the time index of the sample. After the first 12 days of the flight a problem caused intermittant preformance of the air pumps. Only measurements when the pump flow rate was greter than/equal to 9 liters per minute are included.
