... Some of them are demonstrated above, and I'll address the "how-to" aspects one by one. ... Save your image as transparent based on the average color of your background tile. ... It will appear to be all one color now, but it's still finely dithered. Use your eyedropper tool to select one of the colors, and fill the bottom layer of your working image with it. ... Either way you go, this method is the first step to for all the other ones, it's from this file that we get our transparency mask. ...

Next: SAS processing Up: Maintenance procedures Previous: Maintenance procedures Contents . Suitable observations should be longer than about 20 ksec, cover all the considered time period, and have different background levels, in particular the highest ones, so the sample should include observations taken at the beginning and end of the science window. It is helpful to consider objects for which no RGS spectrum is expected or to look at the RGS monitor pages. ... Michael Smith 2011-09-20 ...

The approaches mentioned in the section title belong to one family which is called in Newton's book [ 56 ] the short waves or high energy approximation (HEA). It means the scattering by soft particles (or potentials) in the case of the wavelengths short in comparison with the particle size (or correspondingly the case of scattering of high energy particles by the potentials). ...

What is a Handler . ... mod_actions . ... A "handler" is an internal Apache representation of the action to be performed when a file is called. Generally, files have implicit handlers, based on the file type. Normally, all files are simply served by the server, but certain file types are "handled" separately. Apache 1.1 adds the ability to use handlers explicitly. ... The following directives will enable the send-as-is handler, which is used for files which contain their own HTTP headers. ...
