This converts an Observations Window with an AAVSO light curve to a regular Observations Window. An AAVSO ObsWin contains AAVSO specific information, e.g., to filter observations by observer or by band. But an AAVSO ObsWin also has restrictions: one can not manually add a new Observations set to such ObsWin, as the set may not necessarily have all required AAVSO info. 

By converting an ObsWin to a regular ObsWin, you loose all AAVSO specific info, but can for instance start to combine the AAVSO observations with additional Observations sets.

This command only exists if the Observations Window shows an AAVSO light curve. It can not be undone.
