5.1.2 Return a specified scan(s) specified by scan number or source name as a new scantable
Description

Return a specific scan (by scanno) or collection of scans (by source name) in a new scantable. In both case, you can set selection criteria to scanid argument. For source name, unix-style patterns are accepted for source name matching, e.g. ’*_R’ gets all ’ref scans.
