... These sources are much more likely to be gravitationally lensed by intervening galaxies as compared with sources discovered in surveys in other wavebands. ... The effect of lensing by clusters is then discussed briefly. This is expected to increase the source confusion noise in a Planck survey in the directions of clusters, and could provide information about galaxies with flux densities that are too faint to be detected directly by Planck . ... 2 The properties of galaxy--galaxy lensing . ...

... 3.2 CTI correction In CCDs part of the charge released by an absorbed photon is lost during transfer to the readout node. This loss depends on several parameters, in particular on the position where the photon was detected, its energy, the temperature of the CCD, and the saturation of traps by charges preceding along the readout direction. ... The model accounts for the e ects of incomplete charge collection close to the detector surface. ...

... Image Quality of the VLT . Total Optical Control . First light for the ESO VLT unit telescope 1 occurred during the workshop. ... The image shown (Figure 1 ) here was obtained with the VLT on May 16, 1998, in red light (R band), i.e. while the mirror was still uncoated. ... In this diagram (FIgure 2), the measured image quality of the VLT UT1 astronomical images is plotted versus the ``seeing", as measured by the Seeing Monitor, a small telescope also located on top of the Paranal Mountain. ...
