Astroquery: shrinking box size towards the celestial poles?

https://github.com/astropy/astroquery/blob/ac719ee24bdf5b66bd93b84100f13a7099c0d1f7/astroquery/sdss/core.py#L1009

I think using "(ra - dr / cos_dec, ra + dr / cos_dec, ..." is better. Otherwise the actual box size will shrink towards the celestial poles. Also, adding boundary detection near RA~0/360 might be helpful.

I've been using astroquery for a while, which helped a lot in my research. Thanks anyway!

Actually it would be good to get rid of this workaround and use what sdss does with their radius search:

SELECT  TOP 10 p.objid,
   p.run, p.rerun, p.camcol, p.field, p.obj,
   p.type, p.ra, p.dec, p.u,p.g,p.r,p.i,p.z,
   p.Err_u, p.Err_g, p.Err_r,p.Err_i,p.Err_z
   FROM fGetNearbyObjEq(258.25,64.05,3) n,   PhotoPrimary p
   WHERE n.objID=p.objID 

alternatively define a dr_ra and dr_dec separately and use that one.
