New description:
John Cremona tells me that: "All data for elliptic curves of conductors
from 130k to 200k is at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/ and also as a tar
file at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/ecdata-2011-10-26.tgz
-- not to mention at http://code.google.com/p/ecdata/ !"
The goal of this ticket is to:
(1) Create a new drop-in-replacement sqlite database that has the data up
to level 10000, which will be included standard with Sage.
(2) Create a new sqlite database that has the data up to level 200000,
which will be an optional spkg.
This is complicated because the current packages in Sage use ZODB. Also,
Cremona's database format has changed somewhat.
There is now a patch that depends upon #11642 (which depends upon #11640).
You can find updated elliptic_curve and database_cremona_ellcurve spkgs at
[http://wstein.org/home/ohanar/cremona-database/].

Replying to [comment:54 rohana]:
> I've posted a new spkg with your expanded tables, same location as
before.
Not really same location as before, I updated the ticket description.
