scipy.optimize.curve_fit
This must be installed in order to use the Ginga displays instead of DS9. Using ginga has the advantage that the imexam() loop is now event driven. Issuing the command:
viewer.imexam()
Will print out the available examination command keys. The user can then press the “i” key while the mouse is in the graphics window, all subsequent key-presses will be grabbed without blocking your terminal command line. If you wish to turn of the imexam keys you can press either the “i” key a second time or the “q” key. A notification message will appear on screent that imexam mode has either started or stopped.
