                http://lsst-qserv-dax01.ncsa.illinois.edu:5000/db/v0/tap/sync

(1.4) ForcedSource searches (RunDeepForcedSource table)

One reference query here is to start with an Object ID and retrieve all the ForcedSource measurements associated with that object.  That is a direct foreign-key relationship between the two tables and is trivially expressed in SQL.  This query must be highly performant - the goal should be for this to take only a few seconds.  (The formal LSST requirement is <10s, but we should aspire to be quite a bit faster than that.)

Input: OBJ_ID

URL:

curl -o forcedSource.json \

-d 'query=SELECT+<column names>+FROM+sdss_stripe82_01.RunDeepForcedSource+WHERE+objectId=OBJ_ID;' \

(3) Basic light curve / time series viewer query on RunDeepForcedSource

For returning the magnitude:

Computing a calibrated magnitude requires correcting the observed flux for the photometric zero point.  This requires a join between the RunDeepForcedSource table, for the information about the individual observations, and the Science_Ccd_Exposure table (for a per-visit-image photometric zero point).

Input: an objectId :

Example:

Tested (Gregory Dubois-Felsmann ):

For WISE Light Curve Query:


Step 1. Get the object id (the column cntr) from the object table: target RA = 10.68479, Dec = 41.26906, radius = 0.027777777777777776 deg

curl -o wiseObjectsCone.json\

-d 'query=SELECT+*+FROM+wise_00.allwise_p3as_psd+WHERE+qserv_areaspec_circle(10.68479,41.26906,0.02777777777777777);\

' http://lsst-qserv-dax01.ncsa.illinois.edu:5000/db/v0/tap/sync


Step 2. Pick one object id from Step 1 result to query the forced sources (the column cntr_mf):   

curl -o wiseForcedSourceConeObjId.json\

-d 'query=SELECT+*+FROM+wise_00.allwise_p3as_mep+WHERE+qserv_areaspec_circle(10.68479, 41.26906,0.027777777777777776) +AND+ cntr_mf = 98140801351043831;\

' http://lsst-qserv-dax01.ncsa.illinois.edu:5000/db/v0/tap/sync


Note: The qserv_areaspec_circle can be removed from the second step (search the forced sources) after Qserv improves the WISE data table indexing.

    See  DM-8237 - Getting issue details... STATUS : we need to edit the sample queries accordingly.
