Configuration > Information entry "Longitude/latitude (J2000)" is faulty

[Shriramana Sharma]

I am using Stellarium 0.12.4 on Kubuntu Precise 64 bit.

Currently in the Configuration > Information pane there is an entry "Longitude/latitude (J2000)". Hovering over this gives the tooltip "Galactic coordinates, equinox of J2000".

First, the galactic coordinates are not dependent on any equinox unlike ecliptic or equatorial coordinates. So the qualifier "J2000" is misleading. The galactic coordinates were originally defined in terms of B1950 but they do not themselves relate to the equinox of any epoch. Further, the adjective "galactic" is missing in the config window so it is not directly clear what long/lat are referred to. (It should be clear without requiring the tooltip.)

Apart from this, selecting or deselecting this option doesn't have any effect on the display of the Galactic coordinates in the info area on the top left corner of the screen. (Thankfully there is no "J2000" or other such misleading adjective there, though.)

Please fix all these problems. Thank you!
