The Big IdeaConnect novice researchers to expert-developed software so the novices can do science sooner.

Outline

• A little astronomy

• reducer notebook demo

• reducer widget architecture (pure python)

• make-your-own-widget demo

Thermal noise(dark current)

Combine calibration images

• Take 10+ of each calibration image

• Combine to avoid adding noise to data

Note to self: notebook

widget architecture

Every red box is a subclass (directly or indirectly) of

reducer.gui.ToggleContainerWidget

Outermost box is a reducer.gui.ToggleGoWidget
