The WFPC2 CCDs are thick, front-side illuminated devices, with a format of 800x800, 15x15 ? m multi-pinned phase (MPP). MPP allows CCD exposure with the total inversion of all phases. The Si-SiO 2 interface, at the surface of the CCD, is pinned at the substrate potential, directing signal charge away from the Si-SiO 2 interface states towards the buried n-channel. Figure 4.1 shows a schematic which illustrates the principle of MPP (modified from Janesick et al. ... 800 800 . ...

... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

Next: How to get Up: Introduction Previous: Introduction . ... However, we cannot make all our observations at the same time, or at the same place in the sky. ... To do this, we must distribute the observations so that the main independent variables (such as airmass, star color, and instrumental temperature) are uncorrelated with each other. ... As some (like temperature) are inherently likely to be correlated with time, it is doubly important that others (like airmass) be uncorrelated. ...

. You can compare any two versions of a file that is under the control of SCCS with the sccsdiff command: /usr/sccs/sccsdiff -r version -r version s. filename . Using this command produces a line by line difference between the two versions of the file. Results are shown in the same format as that produced by the diff command. Examples .

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...
