Next: Particle Background Rejection Up: Detection Efficiency Previous: Front Illumination . ... The method requires that the CCD substrate be etched from the rear towards the depletion layer boundary. The device can be illuminated through this rear surface, which has a much thinner dead layer than the electrode side. ... The corresponding detection efficiency data are presented in Figure 7, and compared with the predicted data for a 20 m thick depletion layer. ...

... There are many, many data files for this program, but to start you would probably like to look at the reduced spectra, and then go back to understand how they got the way they are and how the calibrations might be improved. The reduced wavelength and flux files have suffixes of .c0h and .c1h (for a complete explanation of file suffixes, see Table 35.1 ). ... For a quick look, we need to use fwplot , a task in stsdas . ... cl>fwplot z2bd010ct.c1h This produces the plot shown in Figure 35.12 . ...

I recommend reducing the back ground data first, simply because they are needed when averaging point data for the visibility normalization. ... I plot 4 channels at a time, by setting the selection directive initally to Selected and entering the selection 1-4 into the field just below the directive button. ... Write an X into the BG column if you delete this channel based on the back ground data (e.g. channel 11), or write the rate into it when larger than 1.0. ... Back to tour page . ...

4.0 Multiple Output CCD Optimization . ... For the reasons described in the section above, we are rapidly approaching the limits to decreasing the noise spectral density of on-chip CCD amplifiers using smaller amplifier geometries. ... Our testbed for optimizing multiple output CCDs is our ADAPTIII CCD – a very high frame rate (10,000 frames per second), low noise (less than 3 electrons rms.), back illuminated CCD designed for adaptive optics and wavefront sensing applications. ... Pixel Format . ...

. This section describes how to convert raw filterbank data to our standard archive format. From there is it relatively easy to obtain arrival times. The data reduction is a multistage process. You must learn about each in turn. Note: production and reduction of the filterbank data uses the environment variables tpool and fptmpool a lot. Data goes into tpool and the finished archives end up in fptmpool. (Note environment variables need a $ sign in front of them to activate them) .

A classical effect which I found kind of an easy way of doing with the gimp. There's a filter in PS called ``Wind'' which would make this a lot easier..

Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

NOTE: Analyz routines for L-band receivers use OLD gain & noise diode values!
