Synphot Data User's Guide

Preface

---

Although synphot is a general purpose package for synthetic photometry, much of its utility for Hubble Space Telescope users arises from the detailed models of HST instrument throughputs that are stored in the Calibration Data Base system (CDBS) and available for download at:
www.stsci.edu/resources/software_hardware/stsdas/synphot

Available keywords for synphot tasks are defined by the graph and component tables (located in mtab$), and actual response curves for supported bandpasses, including throughputs for all past and present instrument modes for HST as well as groundbased photometric systems, are stored in throughput tables (located in comp$).

This document describes the use of synphot tasks with the observing modes available using these associated data files, as well as some specific issues affecting particular HST instruments.

This document is not a general guide to synphot. For more information on synphot tasks and capabilities, please see the Synphot User's Guide, available for download at:
