We here present an overview of Celldetect , a source detection program for Chandra. ... Celldetect identifies point sources in the presence of background. ... At each point where a detection is attempted, celldetect uses an appropriately sized cell. ... The background statistics in celldetect change as the cell size increases. ...

... This is called disk buffering , and the memory used for the purpose is called the buffer cache . Since memory is, unfortunately, a finite, nay, scarce resource, the buffer cache usually cannot be big enough (it can't hold all the data one ever wants to use). ... On the one hand, data that is written is often soon read again (e.g., a source code file is saved to a file, then read by the compiler), so putting data that is written in the cache is a good idea. ...

. When you enter a command it invokes a program. While this program is running it is called a process . Although there is only one copy of a program, any number of processes can be invoked which run this program. There are several commands which allow you to manage the processes that belong to you. You cannot do anything with processes belonging to other users. Running processes in the foreground . Running processes as background jobs . Managing background jobs . Monitoring processes . Killing a process .

CCD Performance . ... The dark current appears to have two components: one from electronic sources in the CCD, and a second component whose strength correlates with the cosmic ray flux. ... As of this writing, the " DARKTIME" keyword in the WFPC2 image headers does not reflect correctly the actual time during which the CCD collects dark current. ... External exposures of 180s or longer made with the serial clocks off (CLOCKS=NO; the default setting) suffer an additional 60s of darktime (restart=1). ...

... This file is read by the pointing program and the irigServ program when they are started. Both of these programs are running on the vme pointing crate. ... Instead of rebooting the pointing crate, we just stop the pointing program and restart it.. this gets around a race condition when the pnt clock is being syncronized and the pointing program is asking for the utcToUt1 info.. ... Leap seconds are transmitted 0 hr 01jan UTC. ... Have the pnt program and irigServ program reread the year file. ...

If the Listen specified in the configuration file is default of 80 (or any other port below 1024), then it is necessary to have root privileges in order to start apache, so that it can bind to this privileged port. ... The recommended method of invoking the httpd executable is to use the apachectl control script. ...

... Bit Fields . Bit Fields: Practical Example . ... NOTE: The combination of pointers and bit-level operators makes C useful for many low level applications and can almost replace assembly code. ... To illustrate many points of bitwise operators let us write a function, Bitcount , that counts bits set to 1 in an 8 bit number ( unsigned char ) passed as an argument to the function. int bitcount(unsigned char x) { int count; for (count=0; x != 0; x>>=1); if ( x & 01) count++; return count; } . ...

GPLOT is written for those who want a lot of flexibility in creating plots and are not satisfied with standard plotting facilities in other GIPSY applications. ... GPLOT is command driven and therefore cannot be compared with a program like CPLOT which is controlled by keywords. ... It processes plot commands like frame , move , draw , quit etc. with or without parameters. ... A destination is set with command device . ... In this document such command files are used as recipes for example plots. ...

T he Siding Spring Survey (SSS) is a Near-Earth Object search program that utilises the 0.5-m Uppsala Schmidt Telescope at Siding Spring Observatory, N.S.W., Australia. ... The mission of the Siding Spring Survey is to contribute to the inventory of near-earth objects (NEOs), or more specifically, the potentially hazardous asteroids (PHAs) and comets (PHOs) that may pose a threat of impact and thus harm to civilization. ...

Automatic Detection of NEOs in CCD Frames . ... CCD frames obtained with modern telescopes with robotic operation allow carrying out standard observation programs for detection of peculiar objects on stellar backgrounds, as is the case of Near Earth Objects (NEOs). ... In this paper, we present original algorithms for automatically detecting dim NEO images in telescope frames, considering both sidereal and differential tracking [2]. ...

... Wolfram ----------------------------------------------------------------------------- We intend to use aperture photometry with aperture scaled by seeing. We will test how well this works before making a final decision. ... These tests should also clarify the significance of the finding. ... The question is this: When we do the counter-rot of the frames, and then co-add, how do we know that the features we see are true rotating features, or simply remaining features seen in single frames? ...

Most radio and modem clocks used for a primary (stratum-1) NTP server utilize serial ports operating at speeds of 9600 baud or greater. ... In order to reduce these errors, a set of special line disciplines and stream modules can be configured in the Unix kernel. ... Note that not all Unix kernels support line disciplines and of those that do, not all support System V streams. ... There are two line disciplines and a special streams module included in the distribution. ...

Starting Apache on Windows . Starting Apache on Unix . ... If the Port specified in the configuration file is the default of 80 (or any other port below 1024), then it is necessary to have root privileges in order to start Apache, so that it can bind to this privileged port. ... As an alternative to invoking the httpd binary directly, a shell script called apachectl is provided which can be used to control the daemon process with simple commands such as apachectl start and apachectl stop . ...
