Talk:List of stars in Vulpecula

From Wikipedia, the free encyclopedia

When you making the star table by constellations, to find the distances in light years and parsecs, you should find it in WIKISKY.ORG under the external links in Aquarius constellation and you should find it. To convert from parsec to light year, multiply by 3.2616 or divided by 0.3066 since if you find only in parsec. The precision of distances for both light years and parsecs must be down to hundredths or thousandths while in WIKISKY.ORG, it has a precision down to thousandths. If the distance has a digit like ten thousandths (hundredths), if your doing in thousandths, ten hundredths (tenths) and hundred hundredths (whole number), don't put zeros down to hundredths or thousandths. if it is a whole number, don't put the decimal point nor putting the point then zeros. Also for right ascension and declination, in seconds, must have precision down to hundredths and opposely to distances, you should have zeros down to hundredths, like in whole tenths and in whole numbers, you should put a decimal point and two zeros. Even if the distance is known in light years already, you should add these numbers down to hundredths or thousandths to make it more precise if necessary, and same procedure for right ascension and declination if already have it if necessary.

Definitely not; such accuracy is terribly misleading. Hipparcos measured nearby stars with a good accuracy (max. accuracy tenths of a light-year). Stars further out should not use three-digit accuracy. The situation is even worse in the case of very distant stars; given values are more or less arbitrary (error bars being more than 100%: according to Hipparcos, Deneb's parallax is 1.01 +1.56 −1.55 mas meaning the star could be anywhere beyond 389 pc). Then there are stars which have erroneous values in the Hipparcos Catalogue (for example, the Pleiades and Beta Centauri).--JyriL ^talk 13:20, 28 December 2006 (UTC)
