Version 0.1 of the SDSS PSFs: First published PSFs and already sent to MNRAS This is the first version of the SDSS PSFs paper that has been sent to the MNRAS journal. At this point the PSFs are ready to be published so any person can use them. The tag/version "v0.1" is the one that appears into the paper already sent to the journal and because of that, they are published at the IAC Stripe82 web page: http://research.iac.es/proyecto/stripe82/pages/advanced-data-products/the-sdss-extended-psfs.php
