How do I cross match my catalog with Legacy Survey catalog [closed]

Question

Hi Datalab team,

I saw a few questions on this issue, but I do not find the correct example. I have a list of (ra, dec), ~ 1000 objects. Could you share the example of cross-match to ls_dr8.tractor table to get the mag_g, mag_r, mag_z, mag_w1, mag_w2 and the corresponding fluxes and errors?

Thanks,

Huanian
