Data for stars is listed in order of distance from the requested location.

basic output:

star: (db-sequence) (ra) (dec) (distance) (Nmeasure) (positional-chisq) (average.flags) (objID) (catID) : see notes below g r i z y (these average filters depend on the db schema) (g:ave) (r:ave) (i:ave) (z:ave) (y:ave) (g:err) (r:err), etc (g:chisq) (r:chisq), etc ... repeat for other stars

-meas / -m add the following for each measurement of the star:

(mag:cat) (mag:rel) (mag:err) (time) (RA.offset) (DEC.offset) (photflags) (dbflags) (photcode.number) (photcode.name) (FWHM_x) (FWHM_y)

Notes:

db-sequence is not really useful (internal seq number that is not

guaranteed to stay fixed)

ra & dec in decimal deg distance from reference coordinate in arcsec objID : unique object ID within this catalog (spatial subdivision of

the dvo db tables; 32bit)

catID : unique catalog ID g:ave : average magnitude for object (careful -- this may or may not

be up-to-date wrt to all measurements in db; clipping and relative photometry may or may not have been applied)

g:err : formal error on g:ave g:chisq : chi-square of g:ave calculation (assuming constant magnitude) mag:cat : magnitude applying only nominal system zero point, without

applying relative photometry offsets, if known

mag:rel : magnitude after relative photometry is applied. mag:err : error on individual measurement time of measurement RA.offset, DEC.offset from average position in arcsec photflags, dbflags : bit-flags from the photometry analysis or from

database-level crawlers

photcode.number,name : what is the source of this magnitude? FWHM_x,y in pixels
