quasars. The frames can be used to make light curves of quasar images
and field objects. From quasar light curves, one may measure time
delays and flux ratios, analyse variability and chromaticity, etc.
These direct analyses/measurements are basic tools for different
astrophysical studies, e.g., expansion rate of the Universe, mechanism
of intrinsic variability in quasars, accretion disk structure,
supermassive black holes, dark halos of galaxies (dust, collapsed dark
matter, smoothly distributed dark matter,...)http://dc.zah.uni-heidelberg.de/tableinfo/liverpool.rawframesIsServedByGAVO Data Center ObscoreLens Image ArchiveGAVO Data Center TAP servicehttp://dc.zah.uni-heidelberg.de/lensunion/q/im/siap.xml?https://dc.zah.uni-heidelberg.de/lensunion/q/im/siap.xml?GETapplication/x-votable+xmlPOSICRS Position, RA,DEC decimal degrees (e.g., 234.234,-32.46)pos.eqcharSIZESize in decimal degrees (e.g., 0.2 or 1,0.1)degcharINTERSECTRelation of image and specified Region of Interest.charFORMATRequested format of the image datachardateObsEpoch at midpoint of observationdtime;obs.exposurecharbandpassIdFreeform name of the bandpass usedinstr.bandpasscharobjectObject being observed, Simbad-resolvable formmeta.idcharresponseformatFile format requested for output.meta.code.mimecharmaxrecMaximum number of records returned.
