Hello all


I am working through the Machine Learning for Astronomy with Scikit-learn tutorial, but got stuck with notebook 08 (regression_example).


The script fetch_data.py in the directory ../data/sdss_photoz is supposed to download the colors of the 400,000+ galaxies from the Sloan Digital Sky Survey, but this does not work. The URL http://www.astro.washington.edu/users/vanderplas/pydata/ is broken, e.g.: http://www.astro.washington.edu/MOVED?http://staff.washington.edu/jakevdp/


Is there an alternative source from which to download the data. And, similarly, an alternative source for the set of spectra for notebook 09 (Dimensionality Reduction Example).

Thanks a lot,
Matteo
