Migration to Python3 in progress…

GLEAM is avaiable as a python module and is on its way to be implemented as a standalone app for macOS. In future, simply download the lates release and double-click to run… To use the full framework however, clone the repository and add it to your PYTHONPATH (e.g. in your .bashrc file).

GLEAM inherits a requirement from GLASS swig. On linux, also make sure that python2-dev (or similar) and python-tk is installed. For example,

sudo apt install swig python-tk python2-dev

To install GLEAM manually, simply open the terminal and run

./configure
./install

This will unpack, compile, and install all the necessary dependencies. It might need some tinkering, so if any problems arise feel free to contact me.

The synthetic imager. The ReconSrc class provides complete functionality of the synthetic imager and can be initiated with a mass maps and observations loaded as a LensModel (gleam.utils.lensing) and LensObject (gleam.lensobject) object respectively.

Framework for reading astronomical coordinates such as J2000, RA/Dec, etc. Is able to convert between different coordinate systems, and interfaces particularly well with the CFHTLS MegaPipe pixel coordinate system.

Reads in a single .fits file and extracts general information on the observation. Also contains several plotting procedures which visualize the data.

Reads in a set of .fits files and extracts general information on the observation in different bands, analogously to skyf.py (importing skyf.py). Visualizes data as stacked or palette image.

Inherits from SkyF. Additionally extracts properties important for gravitational lenses and lensed sources. Visualizes these properties on top of inherited plotting procedures.

Inherits from SkyPatch. Additionally extracts properties important for gravitational lenses and lensed sources, analogously to lensobject.py. Visualizes these properties on top of inherited plotting procedures as stacked or palette image.

A simple peak finder to extract lens and source image positions. Uses very crude procedures, whose parameters have to be fine-tuned. Provides an automatic lens detection feature to the LensObject class.

GLASS config-file generator. Features a sync and config reading feature with LensObject class. Can be used to write config files for LensObject class instances, or to extract config files from LensObject class instances.

• TODO: Write a main method for usage as script!

Several utility features such as custom color maps, basic lensing computations, plotting functions, etc. A general LensModel object is included as well with which a GLASS state or any kappa map can be read in.

• Still in work…
• Implemented features: reading in .fits files, applying masks of several shapes, and saving as .json files.

Two dimensional, Sersic mapper. Calculates and visualizes profiles and maps.

Two dimensional, softened power-law elliptical potential SPEP mapper. Calculates and visualizes profiles and maps.

Two dimensional, softened power-law elliptical mass distribution mapper. Calculates and visualizes profiles and maps.

GLEAM interfaces with GLASS, which is why GLASS is included in as a package in src. To install it on macOS simply use the compile and install scripts. On linux, glpk sometimes installs its build library in src/glass/build/glpk_build/lib64 which needs to be renamed to src/glass/build/glpk_build/lib. If the subsequent install fails, it might be worth renaming it manually.
