componentlist.open - Function

1.2.1 Construct an componentlist from the data in an CASA table


Description

Use this constructor to construct a componentlist tool by reading the data from an CASA table. To ensure that this table contains all the necessary columns and to allow the table format to be enhanced in the future, it is highly recommended that the table be created using a componentlist tool1.

The table that contains the componentlist may be opened read-only by setting the readonly flag to True. When this is done some of the functions in the componentlist tool cannot be used. These include the “set”, “convert”, “remove”, “replace”, “purge”, “recover”, and “sort” functions.
