ZTF Photometric Requirements Document

Introduction

The goal of this document is to outline the deliverable products and performance requirements for the ZTF Data Systems. This is to ensure that ZTF can achieve the science goals described in the ZTF Science Requirements Document. The requirements listed below apply lessons learned from PTF and iPTF to specify what should be possible with ZTF. In this document we will try to review the current status, precision and accuracy, of the PTF pipeline, and suggest ways to improve it.

We also provide the list of required pipeline steps, meta data and data products to be stored. Some of this requirements may have implications to hardware apparatus (e.g., flat field screen?), and some to computing requirements and data storage.

The primary science goals for ZTF, as outlined in the science requirements document, are listed below:

  1. Discovery of Fast, Young, and Rare Transients at near real time;

  2. Searches for Electromagnetic Counterparts to Gravitational Wave Sources;

  3. Producing high precision light curves for all sources;

  4. Asteroid and streaks Discovery.
