impro

This repository contains an assortment of routines written in IDL for reducing and analyzing multiwavelength imaging and spectroscopy of galaxies.

Some of the code highlights included with impro:

  • iSEDfit - fully developed, documented, and publicly released software which uses Bayesian inference to extract the physical properties of galaxies from their observed broadband photometric spectral energy distributions. Please see http://www.sos.siena.edu/~jmoustakas/isedfit for details.

  • Routines to read and interact with the outputs from a broad range of stellar population synthesis models, including BC03, Pegase, Starburst99, and FSPS.

  • Routines for inferring the physical conditions (metallicity, temperature, dust content, etc.) and star-formation rates of star-forming galaxies and HII regions from the strength of their nebular emission lines.

  • Routines to construct and model the luminosity and stellar mass functions of galaxies using a variety of parameterizations (single, double Schechter, double power-law, etc.).

  • Routines to fit and model the optical stellar continuum and emission-line spectra of galaxies, and to measure a variety of spectral indices (e.g., Lick indices, D4000, etc.).

As usual, the code is provided as-is, with no guarantee of accuracy or success. However, if you are interested in contributing actively to impro send me a note!

Installation

Download the bleeding-edge version of the repository from Github using the following command:

git clone http://github.com/moustakas/impro.git

Alternatively, you can download a tarball or zip file snapshot of the code base by navigating directly to github.com:

https://github.com/moustakas/impro

Next, add an ${IMPRO_DIR} environment variable to your appropriate startup file. For example, if you use tcsh, add the following line to your .tcshrc file:

setenv IMPRO_DIR /path/to/impro

Finally, add the 'pro' subdirectory of ${IMPRO_DIR} to your IDL path. Using the example above, you would add:

setenv IDL_PATH $IDL_PATH{:}+${IMPRO_DIR}/pro

to either your .tcshrc or .idlenv startup file.
