The Catalog of Unidentified Cometary Emission lines

  Data Set Overview
  =================

  This data set contains tables of unidentified spectral emission lines and
  other ancillary information in a variety of comet observations. All these
  originally unidentified lines have been taken from the reference papers
  without adding or removing lines or using selection criteria.

  Archive Package Overview
  ========================
  
  The data are presented in single .csv files with definitions. Entries that
  could not be found are filled with the value 'UNK' (Unknown) to represent
  there is no data for that entry in the reference papers. The units between
  different data may change and the label will have the proper units for the
  entry.

  The following are the categories you will find in the data.

Known Issues or Problems with the Data
======================================
  The data for the given 12 comets have been taken from the papers in the
  different per-reviewed journals. Take into consideration that, the data are
  not homegenious due to various methods used for results in calculations by
  different authors.
