I'm trying to explore the forced photometry from MzLS and compare to the tractor photometry as a function of observing conditions. But I don't find any forced-photometry measurements in the database. E.g., the following query returns no results
SELECT f.ls_id, f.ls_ccd_id, t.ra, t.dec
FROM ls_dr8.tractor as t
JOIN ls_dr8.forced as f ON (f.ls_id = t.ls_id)
WHERE t.dec > 40
SELECT c.ra, c.dec, f.ls_ccd_id, c.camera
FROM ls_dr8.ccds_annotated as c, ls_dr8.forced as f
WHERE (f.ls_ccd_id = c.ls_ccd_id) AND c.dec > 40 AND c.camera='mosaic'
Are the MzLS forced-photometry loaded for the "North"?
