Next: Reduce point data Up: Quick Guide Previous: Print form sheets Contents . You should reduce this data of type ``scan'' before anything else. ... Plot the background rate (four channels at a time) versus time. ... Use P ROCESS BG if you want to replace edited scans with an average value from other valid scans in the same channel. ... The reason for reducing the background data first is that average will not average the point data of a scan for which no background data exists. ...

... Posts tagged ?background? ... Probability density functions are another way of summarizing the consequences of assuming a Gaussian error distribution when the true distribution is Poisson. We can compute the posterior probability of the intensity of a source , when some number of counts are observed in a source region, and the background is estimated using counts observed in a different region. ... In both cases a background of 200 counts collected in an area 40x the source area is used. ...

. To run a foreground process as a background job: . 1. Suspend the foreground process. 2. Enter the bg (background) command to move the process into the background. For example: lpr -Pps23 part[1-8].ps ^Z Stopped bg [1] lpr -Pps23 interface.ps jobs [1] Running lpr -Pps7 interface.ps . This starts a foreground process to print several files. The process is then stopped and the job moved into the background. The state of this job is then checked.

... Someday, when people have begun to live on other planets or their moons, these worlds might develop their own flags. In this activity, you get to design a flag for your favorite world. ... The flag can just have colors and symbols, like many Earth flags do, or it might highlight some of your planet's most interesting places to visit. For example, a Mars flag might have a red background, because the rusty sands of Mars look red from space. ... Flags of the World: http://www.fotw.net/flags/ . ...
