The files are named in accordance with the following convention: yyyydddhh_ttt_ vv.PNG where yyyydddhh = Start date of file (yyyy = Year, ddd = Day of Year, and hh = Hour of Day) ttt = Plot type (SPECTRA = mass-time spectra, or LINE = mass time series) vv = Version number of data ( 01, 02, ..., etc.) The browse directory contains a separate subdirectory for each day. The daily subdirectories are grouped by year into yearly directories. The yearly directories are named for the year, 2004, 2005, and so forth. The daily subdirectories are named with the ordinal day-of-year, 001, 002,...366. Each daily directory contains eight files, four mass-time spectra and four mass time series. yyyydddhh_SPECTRA_vv.PNG - Mass-time spectra browse plots yyyydddhh_SPECTRA_vv*.LBL - PDS label for SPECTRA plot file of same base name yyyydddhh_LINE_vv.PNG - Time series browse plots yyyydddhh_LINE_vv.LBL - PDS label for LINE plot file of same base name
