The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.
undo
undo the previous command
Undo the affects of the previously entered xspec command.
| Syntax: | undo |
|---|
New for xspec version 12, the undo command will restore the state of
the xspec session prior to the most recently entered command. The current
implementation does not allow restoration to more than one command back,
so calling undo repeatedly will have no effect. Also, a plot
command cannot be undone.
