... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

... Publications with ESO Data . ... The tools have been developed for ESO by a team of astronomers at the Institute for Astro- and Particle Physics at the University of Innsbruck, as part of an in-kind contribution to ESO , which includes as well a model of the sky emission and transmission spectrum at Cerro Paranal. ... Skycorr provides an advanced instrument-independent sky-correction tool that removes sky emission in science spectra by means of sky spectra taken at a different time and sky location....
