In the framework of the Gravitational LENses and DArk MAtter (GLENDAMA)
project, we present a database of nine gravitationally lensed quasars (GLQs)
that have two or four images brighter than r = 20 mag and are located in the
northern hemisphere. This new database consists of a rich variety of follow-up
observations included in the GLENDAMA global archive, which is publicly
available online and contains 6557 processed astronomical frames of the nine
lens systems over the period 1999−2016. In addition to the GLQs, our archive
also incorporates binary quasars, accretion-dominated radio-loud quasars, and
other objects, where about 50% of the non-GLQs were observed as part of a
campaign to identify GLQ candidates. Most observations of GLQs correspond to an
ongoing long-term macro-programme with 2−10 m telescopes at the Roque de los
Muchachos Observatory, and these data provide information on the distribution
of dark matter at all scales. We outline some previous results from the
database, and we additionally obtain new results for several GLQs that update
the potential of the tool for astrophysical studies.Comment: Accepted to A&A; 32 pages. Tables 4-6, 8-11 and 13-16 are only
