M31付近を中望遠で撮った写真の wcs.fits を leda-get-votable.py に渡して銀河のデータを取得すると、M31 のデータが入っていなかった。

矩形の頂点の座標が、以下の時、

top-left: 1.6886829535187702, 30.367468713549176
bottom-right: 23.956642040157973, 39.29991228113341
bottom-left: 0.8618865859973092, 24.05345124489381
top-right: 0.8848739783242575, 47.058537285933326

HyperLeda に問い合わせるSQLクエリの WHERE が以下のようになっていた。

al2000<23.956642040157973 and al2000>0.8618865859973092 and de2000<47.058537285933326 and de2000>24.05345124489381 and objtype='G'

WHERE の赤経の範囲指定は、以下のようになるべき(最小値は bottom-right の赤経から 24h 引いた値)。

al2000<1.6886829535187702 and al2000>-0.04335795984202662

- 「写野が 0h を跨ぐ場合、leda-get-votable.py で写野内にあるはずの銀河の
  データが取得されない #16」への対応修正(たぶんこれでいけるはず)
- 極が写野に入るケースには未対応

v0.9.3 で対応した(はず)
