Selection of clusters on the number of stars
With the usual options -gt, -lt, -i, one may perform selections
of clusters according to the number of stars for which data
are available. This is useful to know which clusters may be
used for some study, or which should be observed.
Clusters with no data are not recorded, except for ubv
and mk data types.
Please, respect the syntax:
slm data-type option limit
Examples:
slm vsn -gt 30
- selects clusters that have more than 30 stars observed for Vsini
slm ubv -i 5 10
- selects clusters that have between 5 and 10 stars observed
photoelectrically in UBV
