Hello,
This is not a very important question, so don't spend too much time on it.
The lat-lon ordering seems to prevail online ("latitude longitude" vs
"longitude latitude" in google-> 16M vs 470k).
Scisql uses longitude-latitude, presumably because astronomy always says
"RA, Dec" (i.e., lon, lat).
In math, it's always (r, theta, phi) -> (r, lon, lat)
In physics, it's usually (r, theta, phi) -> (r, lat, lon)
In geography, it's always lon, lat.
It seems to make sense for scisql to stick with lon,lat--it enhances
readability for astronomers writing queries. Internally, it looks weird
to write lon, lat rather than lat, lon, but maybe that's okay (until
people use qserv for earth-bound querying)?
Any thoughts?
