HELP: CMT planetary catalogue fields

General Description

  • This catalogue contains all published data from the Carlsberg Meridian Telescope planetary observations.
  • In the tables below you'll find a description of the individual keywords which you may encounter. The first column is a list of the keyword headings. In the second column a 'Q' means that the keyword appears on the query form and an 'I' means that that particular keyword is indexed in the archive. Searching on at least one indexed keyword will always lead to a faster result. The third column describes the value of each keyword.
