Python Synthetic Photometry Utilities

Project Description

This is a prototype module for manipulating spectra. It is intended for it to be used for synthetic photometry, i.e. constructing source spectra and then passing these spectra through an astronomical observatory (e.g. HST, JWST…).

Install the module the usual way:

python install

The spectrum manipulation module will work standalone, whereas the module is designed to work with the HST synphot database, so won’t be much use unless you also install these files. (You don’t need to install the synphot software; only its datafiles.) You can get them from

You must define the environment variable PYSYN_CDBS to point to the top level directory where you have installed these files.

If you have questions about this module, send mail to and it will get to the appropriate person.

The current revision is $Rev: 2176 $.

It has the following dependencies:
  • numpy v1.0 or higher
  • PyFITS v1.1 or higher
  • matplotlib v0.9 or higher
