deselect |
This procedure is used to remove previously selected index numbers from the stack.
Data can be de-selected by using selection criteria in the same way as in select.
Data can be de-selected based on entries in the index file, such as source name, polarization type, IF number, etc. For a complete list of eligible parameters use the procedure listcols.
See the discussion on "Select" in the User's Guide for a summary of selection syntax.
The selection criteria are ultimately passed to the io class's search_index via the _EXTRA parameter.
select, source="ORION" ; select all ORION data deselect, scan=15 ; remove scan 15, perhaps it's bad deselect, ifnum=1 ; remove the IFNUM=1 data
