ICRAR staff and students have developed multiple web-based tools to help with various tasks astronomers come across in working life.

Cosmology Calculator

Make various distance and other cosmological calculations based on custom set parameters.

What’s Up

Plan observing by finding out what’s in the sky above most currently used telescopes.

Astro Map

AstroMap is an [R] tool for generating sky projection maps for astronomical surveys. This tools allow a user to plot full celestial sky maps of astronomical surveys and objects for a number of different map projections. They user can select to plot from library of current and upcoming surveys, or design their own survey layout.


SpecGen is an [R] based package which allows users to generate simulated galaxy spectra using a number of input parameters and databases of mock galaxy spectra. Simulated spectra can either be produced individually, in batch mode from an input text file, or from a user-defined grid over a specific multi-dimensional parameter space (currently limited to 50 sources).


SpecFit is an [R] based package which allows users to display, edit and analyse 1D spectra. A spectrum is uploaded using a user-defined set of paramerters and then be displayed in various ways using multipule options. SpecFit allows the user to measure emission and absorption line fluxes, and manually and automatically assign redshift. Spectra and line fit tables can then be saved in various formats.


Hyper Fit is an R package for fitting multi-dimensional data with a hyperplane available at github.com/asgr/hyper.fit. The hyper.fit package has a top level line fitting function that uses downhill searches (optim/LaplaceApproximation) or MCMC (LaplacesDemon) to search out the best fitting parameters for a hyperplane (minimum a 1D line for 2D data), including the intrinsic scatter as part of the fit.

This tool provides VISTA near-IR cutout images for either VST or VIKING VISTA imaging (depending on region).
