SIA search using a box in galactic coordinates

Question

From the examples available I see how to query the list of images available in the NOIRLab archive within a box defined by its center in (RA,Dec) and (width,height) using sia.SIAService.

But I need to do it for a box defined in galactic coordinates (l,b). Is there a function to do that?

A full example would be welcome.

Thanks for reaching out. The IVOA SIA 2.0 standard prescribes that SIA queries be in Equatorial coordinates (i.e. RA and Dec). You would have to do your own transformation of your l,b bounding box to the equivalent ra,dec "box".
