TGRED is a tool to calculate the gravitational redshift and the respective radial velocity. -
Maidanak Observatory Lens Images
Reduced frames of lensed quasar observations from Maidanak Observatory. See the referenceURL for details on the reduction procedure and calibration data. -
Lens Image Archive
A collection of images of lensed quasars from various sources. Included are images from Maidanak Observatory (ivo://org.gavo.dc/maidanak/res/rawframes/siap), Apache Point... -
Gravitational arc candidates in the CFHTLS-Archive-Research Survey CARS
Candidate gravitational arcs in the 37 deg^2 of CFHTLS-Archive-Research Survey (CARS). The data include their post-stamp images, astrometry, photometry (u*,g',r',i'), geometric... -
Astrometric Microlensing Events Predicted from Gaia DR2
From the Gaia DR2 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (µ_tot >150mas/yr) passing a background source in the next... -
Apache Point observations of lensed quasars
Observations of the lensed quasar Q2237+0305 performed between 1995 and 1998. -
Spectra of lensed QSOs (SSAP)
An archive of optical and near-infrared spectra of strongly lensed quasars and the lensing galaxies. The spectra are resolved to about a few Ångstroms and are flux-calibrated.... -
Astrometric Microlensing Events Predicted from Gaia eDR3
From the Gaia eDR3 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (μ > 100 mas/yr) passing a background source in the next... -
Liverpool Quasar Lens Monitoring
This collection includes optical monitorings of gravitationally lensed quasars. The frames can be used to make light curves of quasar images and field objects. From quasar light... -
