AHELP for CIAO 4.6 Sherpa v2

delete_data

Context: data

Synopsis

Delete a data set by ID

Syntax

delete_data( [id] )

Description

The delete_data() function deletes a data set from a Sherpa session by data set ID.

  • id - the id of the data set to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")

Example 1

sherpa> delete_data()

When called with no arguments, delete_data() will remove the default data set from the Sherpa session.

sherpa> print(get_data().name)
obsid_1843.pi

sherpa> delete_data()

sherpa> print(get_data().name)
IdentifierError'>: data set 1 has not been set

Example 2

sherpa> delete_data("src")

If supplied with a data set ID, delete_data() will remove the specified data set.
