Once the results set from the query above are presented in summary form, you can invoke interactive plotting by pressing the "Plot Results" icon. In this case, selecting mu_alpha and mu_delta in the attribute selection box (again, auto-completion is available for convenience) and selecting "Plot type: Scatter" produces a browsable plot - zoom in to see the group of cluster proper motion members offset to (+20,-40) from the general field population near (0,0) - these are Pleiades proper motion members. N.B. when plotting larger row sets, it is advisable to use "Plot type: Mixed Scatter/Density" or even "Select Mode" -> static for reasonable response times in the present implementation.

For cross-querying, note that crossmatch neighbour tables are present in the ESO VST southern hemisphere optical survey ATLASDR1 DB only, and that these do not include "best" match tables or "mates" fields (as specified in the Gaia DPAC CU9 schema) but otherwise are similar with master and slave unique IDs pointing between any two source catalogues within a predefined neighbourhood radius of 10 arcsec. For example, load in the table metadata for ATLASDR1 and TWOMASS by clicking on "Load database(s)" -> "More" and click on the "+" beside each followed by "OK". Clicking on "Show loaded Metadata" will now display ATLASDR1 and TWOMASS in addition to GACS (click on "Hide metadata" to collapse the view when not required) and expand these up to and including the specific table resource required for querying to load the metadata for auto-complete functionality.

For example, load in the table metadata for ATLASDR1 and SDSS DR9 by clicking on "Load database(s)" -> "More" and click on the "+" beside each followed by "OK". Clicking on "Show loaded Metadata" will now display ATLASDR1 and BESTDR9 in addition to GACS (click on "Hide metadata" to collapse the view when not required) and expand these up to and including the specific table resource required for querying to load the metadata for auto-complete functionality.

An example crossmatch query is given here that checks the g-band photometric consistency between the VST ATLAS DR1 survey photometry and that in SDSS DR9:

select gAperMag3, psfMag_g
from atlasSource as a, photoprimary as b, atlasSourceXDR9PhotoObj as x
where gAperMag3 > -99 and psfMag_g < 99 and distanceMins < 1.0/60.0

Line: 34 to 32

In this case the crossmatch is limited at query time to 1 arcsec via the predicate on "distanceMins". Other predicates remove default rows, and provide the relational join between the two source catalogue tables and the crossmatch neighbour table.

Other data holdings presented via the demonstrator include SDSS DR9 ("BESTDR9"), Vista Hemisphere Survey DR1 ("VHSDR1") and the WISE source catalogue (not surprisingly, "WISE"), and all have crossmatch tables present in ATLASDR1 following the naming convention
