RA Values Need Greater Precision #326

Closed AstroRob closed 3 years ago

AstroRob commented 3 years ago

The RA, Dec values in WWT (both in the location widget in the lower right corner, and in the finder tool you get by right-clicking) rounds the RA seconds to an integer value. This is insufficient for accurately identifying locations in the sky; at the celestial equator this means the RA value is only provided in 30 arc second bins.

Offering RA rounded at least to 1 decimal place would help greatly (3" accuracy is sufficient for most WWT browsing needs).

This is applicable to both web and desktop clients.

I tend to agree that another decimal place of precision would be valuable. My only concern would be making sure that the readout never overflows its containing box, especially in the webclient.

Maybe we can have a hover with higher precision that people can copy from as well?

AstroRob commented 3 years ago

Not sure if this gets through… I took too long to enable 2FA so just got dropped from the project.

Having the text copyable would be great, but in my personal workflow I often am taking screen grabs of a region of interest to get the image and the coordinates in a single picture.

If the extra precision is ONLY hidden inside a hover state then that wouldn’t help.

One should note that showing RA seconds as an integer is never done in any other software… I would hope there is be a formatting solution that adopts the standard convention without overwriting elements in the UI.

@AstroRob FWIW the 2FA stuff for the organization only affects certain administrative rights, not core stuff like participating in issues. Drop me a line if/when you add 2FA and I'll definitely add you back to the organization, but I'm pretty sure you won't encounter any limitations if you're not a member.

I've gone ahead and added another decimal point of precision in the webclient.

So helpful! Thanks!

Cheers, Robert
