samreay / surveyvisualiser

A small project I wrote to visualise galaxy surveys. Adding a survey is easy, so long as you have the sky coordinates (RA and Dec) and some sort of distance (redshift perhaps).

Visualising Galaxy Surveys

A small project I wrote to visualise various cosmological surveys.

Add some data to do - the sky coordinates (Right Ascension and Declination) and some distance measure (redshift), and add it to the visualiser.

Has options to output a high DPI top-down figure, and the ability to output a frame for use in creating an animated visualisation (aka a video). A script is provided to turn the output frames into a video via ffmpeg.

See the examples.py script for invocation examples.

See the output directory for figures and videos.

surveyvisualiser's Issues

examples.py fails because of no survey files

In surveyvis/data/ there are only 2df.npy, 6df.npy and sdss.npy on the repository. Because of this, when get_permutations() is called and (for instance) WiggleZ is read in an IOError is generated.

Only the provided data should be provided in the permutations, or all the data should be in the repo (probably a bad idea), or the get_permutation() function should be scrapped for something where the requested survey can be called on the fly.

syntax error class Camera(metaclass=ABCMeta):

when trying the example:
python examples.py

Traceback (most recent call last):

New dependency issue

In a recent commit you added sncosmo as a dependence on line 2 of surveyvis/survey.py. This module is only used for the SupernovaSurvey class and broke my fork (in which I'm not working on SNIa :)).

This dependency should be moved inside the class that uses it to cut down on dependencies for general use.

Metaclass problem

I get the following error message when I attempt to run 'examples.py'
