For collaboration members, when downloading proprietary collaboration data products,
sdss_access requires authentication using the
.netrc file. To set this up, create or
edit a file in your home called
.netrc and copy the following lines, depending on which
SDSS collaboration you are a member of.
machine data.sdss.org login <username> password <password>
machine data.sdss5.org login <username> password <password>
In the above, replace
<password> with your login credentials. The default
SDSS username and password is also acceptable for anonymous access.
chmod 600 ~/.netrc to make the file only accessible to your user.
The default SDSS username and password is different for SDSS-IV and SDSS-V members.
