AAS Winter 2014

By douglase

I am presenting poster #350.02 at AAS223 describing PICTURE and our latest simulations of its sensitivity to the debris disk around Epsilon Eridani. (A PDF copy of the poster, AAS_winter14rev1final).

To illustrate the methods used in the poster, I put together a IPython Notebook demoing visible nulling with M. Perrin’s POPPY package,  I cranked through the FFTs of hundreds of 1024×1024 arrays with, for an intro see my earlier Gist.
The source code used is available from GitHub:

My PICTURE index card handout, reproduced below, illustrates some of the important features of PICTURE, the science and some handy equations if you are taking a midterm on PICTURE:
