Authors should submit a pdf or powerpoint presentation.
However, we strongly urge you to submit pdf over powerpoint as
we will be using a dedicated windows based system for presentations.
Powerpoint often works differently when those created under MacOS 
are displayed in windows based machines.

Please write roses@astrophysics.arc.nasa.gov if you have any questions.

Submissions are due by COB Monday March 6th.

Thanks for your cooperation.
