CIAO 4.1 has been patched to CIAO 4.1.2. The CIAO 4.1.2 release includes many enhancements to Sherpa; read the release notes for detailed information.

Several new contributed Sherpa scripts became available with the release (listed below), which may be downloaded from the CIAO 4.1 Contributed Scripts and Modules page.

sherpa_contrib.profiles - Allows users to create radial (or elliptical) profiles of 2D imaging data, including model fits, from within Sherpa to allow users to visually inspect the quality of the results; see sherpa_profiles (S-Lang or Python help).

Associated thread - Radial and elliptical profiles of Image Data (S-Lang or Python)

sherpa_contrib.flux_dist - Create and plot the distribution of flux values due to the uncertainties on model parameters; see sherpa_flux_dist (S-Lang or Python help).

Associated thread - Calculating Uncertainties by Simulating Flux Distributions (S-Lang or Python)

sherpa_contrib.utils - Utility routines for Sherpa users; see sherpa_utils (S-Lang or Python help).
