| Description: | DATA REPROCESSED and CORRECTED:
The qc_airmass field indicates that the values in the airmass field are set to -9999, the
missing value, when qc_airmass = 1 (the QC bit 1 was tripped). In reality, the values
were set to -1 and will not be filtered out properly by programs that automatically remove
missing values.
The processing code creating this data has been modified and the data reprocessed and
