Conditional intersection on two datatype files

The synatx for conditional intersection described in the previous item has been extended to include a selection on the second datatype also. The complete syntax for the slm is like:

slm "data type 1" -gt "limit 1" -int "data type 2" -gt "limit 2"

Example:

slm ubv -gt 100 -int uvby -gt 50: list clusters that have more than 100 stars in UBV and more than 50 in uvby
