Photometric analysis of stars using PS1 video cells

Introduction

During PS1 observations several cells are set to video mode and a guide star is observed. The measured position of these guide stars is fed back to the telescope tracking system and is used to fine tune the tracking.

It was pointed out that solar system objects might pass in front of a guide star and thus could be detected by a change in measured flux for the star.

The IPP team has been requested to add a new analysis the suite of tools.
