We have used different strategies to translate the various kinds of stellar designation depending on the published ones and existing catalogues. To collect the field stars we have first considered the largest catalogues commonly used like the HD, HD Extension and the Durchmusterungen. Stars in sequences by constellation Star are sometimes identified by the constellation name and a sequential number. We have therefore designed a specific code number to record them containing the constellation code and a key to the bibliographic reference.
Papers sometimes contain multiple tables with individual sequences.
Several stars have therefore the number 1 and the code number contains also the table number to differentiate them.
