HYG Database v4.4 — David Nash (astronexus)星の位置・明るさ・色(8 等まで)。ライセンス: CC BY-SA 4.0。 手を加えたこと: 8.0 等より明るい星だけを残し、太陽を除き、赤経・赤緯・等級・色指数(B-V)だけの小さなデータにしています。この加工したデータは、同じ CC BY-SA 4.0 で配っています(STARS-LICENSE.txt)。Star positions, brightness and colours (down to magnitude 8). License: CC BY-SA 4.0. Changes: kept only stars of magnitude 8.0 or brighter, removed the Sun, and stored each star as right ascension, declination, magnitude and B-V colour index. The processed data is distributed under the same CC BY-SA 4.0 (STARS-LICENSE.txt). https://codeberg.org/astronexus/hyg
Gaia DR3 — ESA / Gaia DPAC望遠鏡の中だけで見える暗い星(8〜11 等)。ESA の Gaia 衛星のデータ(DR3。Gaia DPAC による処理)を使っています。ライセンス: CC BY-SA 3.0 IGO。 出典の表示(原文): This work has made use of data from the European Space Agency (ESA) mission Gaia (https://www.cosmos.esa.int/gaia), processed by the Gaia Data Processing and Analysis Consortium (DPAC, https://www.cosmos.esa.int/web/gaia/dpac/consortium). 手を加えたこと: Gaia の G 等級と色(BP-RP)から V 等級と B-V の近似値を求め、V が 8.0〜11.0 の星を、赤緯 6 度ごとの天球のタイルに分けて、赤経・赤緯・等級・色指数だけの小さなデータにしています。この加工したデータは、同じライセンスで配っています(DEEP-LICENSE.txt)。This work has made use of data from the European Space Agency (ESA) mission Gaia (https://www.cosmos.esa.int/gaia), processed by the Gaia Data Processing and Analysis Consortium (DPAC, https://www.cosmos.esa.int/web/gaia/dpac/consortium). Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement. License: CC BY-SA 3.0 IGO. Changes: kept stars with Gaia G between 7.5 and 11.2, converted G and BP-RP to Johnson V and an approximate B-V, kept V between 8.0 and 11.0, split them into sky tiles, and stored each star as RA, Dec, V and B-V.
