deselect

procedure deselect, [/keep], [_EXTRA=extra keywords]

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.

Examples

    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
 

Uses

select_data delete

Version
