The references may be obtained in several different ways with the command ref which starts an interactive program. The references are written in distinct and uncompressed files located in the directory bda/references. The filename are like "data type.ref", e.g. ubv.ref or vsini.ref.
> ref
For which kind of data? vsn
Give the reference number: 1
Another reference? 10
Another reference? -1
Precise your choice: orb
Give the reference number: 5
Another reference? 0
The answer "-1" displays the list of data types for which references are available. It also permit to change the data type for further query.
> ref -h display information on the command capabilities.
> ref -n Hoag ubv display the references containing the name of Hoag among the authors' names in the UBV references.
The next options work only with cluster data file, so you need to move to a cluster directory:
> ngc 2287
> ref -t ubv list all references relating to the UBV photoelectric data
The option -m is used to get the references after a data query or a selection:
> mk 103 select the MK data for star #103
> ref -m list the corresponding references
> vsn V -gt 280 select large Vsini
> ref -m list the references
