... DBE is used to specify the personality to use in a digital backend that is based on an FPGA. ... RDBE_PFB is the original polyphase filter personality developed by Haystack for the RDBE digital backend ( DAR=RDBE in the station catalog). It is restricted to 16 baseband channels of 32 MHz bandwidth each, lower sideband, with frequencies of 1024-16-N*32 MHz, where N is an integer between 0 and 15. ... Those baseband channels can be as wide as 128 MHz so the full input bandwidth can be covered. ...

... Reliable estimation of the exposure time and sensitivity of NGST observations is essential to the development of feasible scientific programs. The NGST Mission Simulator (NMS) is a suite of web based tools that is being used for observing program and spacecraft design studies. ... The URL for the main page of the NMS web site is NGST NMS . ... These files include: . ... Once the user data has been extracted from the HTTP request file, temporary NMS input files are stored locally on the server. ...

... The Instrument Rotator . ... Guiding . ... This manual discusses operation of the Telescope Control Computer (TCC) from a user's perspective. It is intended to help the programmer of the TCC graphical interface, and to serve as a basis for a user guide for that interface. ... This guide should be used in conjunction with the TCC Operator's Manual and TCC Commands Manual . ... After that you may specify the current instrument using SET INSTRUMENT and acquire a target using the TRACK command. ...

Plans are under way to create a new way of performing non-interactive observations which will be called auto-observing . ... Non-interactive observing with CIMA has for a long time been available with the use of CIMA command files. Contrary to normal command file observing which requires a command file with a set of commands to be executed sequentially, auto-observing will use a list of sources and a list of instructions on how to observe each of the sources. ...

... The directives provided by mod_access are used in <Directory> , <Files> , and <Location> sections as well as .htaccess files to control access to particular parts of the server. ... The Allow and Deny directives are used to specify which clients are or are not allowed access to the server, while the Order directive sets the default access state, and configures how the Allow and Deny directives interact with each other. ... The Allow directive affects which hosts can access an area of the server. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... They are concerned with Attitude Control System of the spacecraft, satellite visibility from tracking stations, limits on the satellite autonomous operations during the orbit, and needs for auxiliary operations with the spacecraft. ... Among the operational constraints the most important one is the number of programmed slews per orbit, which determines the maximum number of radio sources to be observed during one orbit. ...
