Abstract:
ellc is a fast, flexible light curve model for detached eclipsing
binary stars and transiting exoplanets. The model includes the effects
of star spots, Doppler boosting and light-travel time within binaries
with eccentric orbits.
The model represents the stars as triaxial ellipsoids. The apparent
flux from the binary is calculated using Gauss-Legendre integration
over the ellipses that are the projection of these ellipsoids on the
sky. The model can also be used to calculate the flux weighted radial
velocity of the stars during an eclipse (Rossiter-McLaghlin effect).
The main features of the model have been tested by comparison to
observed data and other light curve models.
The light curve model is implemented as fortran subroutines called
directly from a user interface written in python. Several examples and
of its use are included in the distribution. Updates to the code can
be found at https://pypi.python.org/pypi/ellc/.
Description:
INSTALLATION
------------
The instructions below assume that you are installing the software on
a linux system as root user. See https://pypi.python.org/ for help for
installation on other systems or as a non-root user.
Commands entered on the command line are preceeded by "$".
1. Download the compressed tar file ellc-1.1.0.tar.gz.
2. Unpack the archive
$ tar xzvf ellc-1.1.0.tar.gz
This will create a directory ellc-1.1.0
3. Move to the directory created in the previous step.
$ cd ellc-1.1.0
4. Execute the following command to buid and install the software
$ sudo python setup.py install
EXAMPLES
--------
The distribution includes a directory "examples/" that can be used to
reproduce the figures in the paper. See the file "ReadMe.txt" in this
directory for further details.
