Fitting and Modeling 1-D and 2-D Data¶

Workshop goals are to use Sherpa to:

  • Learn the basics of modeling and fitting with Sherpa by fitting a 1D dataset (the spatial profile of the HST/STIS observation of 3C270 from the Introduction to NumPy)
  • Fit a MAST spectrum of 3C 273 (1D with errors)
  • Fit a Chandra image of G21.5-0.9 (2D)
  • Fit the MAST 3C 273 data using the low-level API

Note

Sherpa currently does not support Python 3.

Agenda

  • Sherpa Installation
  • Sherpa Overview
  • 1-D data with errors
  • 2-D Fitting in Sherpa
  • The low-level Sherpa API
