Widgets and astropy: accomplishing useful research with undergraduates

Packages (all on github, pip installable):

astropy/astropy (contributor) core astronomical packages

astropy/ccdproc (co-lead dev) CCD data reduction/calibration

mwcraig/reducer (lonely dev, more welcome) friendly widget-based interface

Widgets and astropy:doing research with undergrads

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

Future• photometry widget

• time series analysis (Lomb-Scargle)

• suggestions?
