Data files containing the Cremona Database of all elliptic curves over Q of bounded conductor: see also http://www.lmfdb.org/EllipticCurve/Q . For a description of how most of the data here was computed, see the ANTS 7 Proceedings at http://www.math.tu-berlin.de/~kant/ants/proceedings.html . For a description of the algorithms used, see the book Algorithms for Modular Elliptic Curves, published by CUP in 1992 (second edition 1997) and available online here: http://www.warwick.ac.uk/staff/J.E.Cremona/book/fulltext/
In merging the data for 400000-409999 the ranges 406000-406999 and 407000-407999 were omitted by mistake. (The data does exist). This will be rectified.
[1,-1,1,-37,-87] is missing, conductor 406598. It will be 406598c1 and the curve with that label will become 406598d1. (Thanks to Bill Allombert for spotting.)
Some of the analytic shas in this range are wrong: 3740 curves have 2.0 in that column in the allbsd table. Needs investigating, and this range will not be uploaded to the LMFDB until this has been fixed.
