... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...

... Before one can use a filesystem, it has to be mounted . ...

. Unix allows you to link two or more commands together using a pipe. The pipe takes the standard output from one command and uses it as the standard input to another command. command1 | command2 | command3 . The | (vertical bar) character is used to represent the pipeline connecting the commands. With practise you can use pipes to create complex commands by combining several simpler commands together. Examples .

The azimuth encoder rack gear is mounted on the inside of the azimuth ring girder. The azimuth encoder turns on this gear as the azimuth moves 0 to 720 degrees. ... The software assumes that this arc length along the encoder rack gear is correct (at a constant radius of 127/2 feet). The error in the radius of the rack gear becomes an azimuth error. To measure the error in the azimuth encoder rack gear, jon hagen built a proximity sensor. ... To compute the az encoder runout error: . ...

... I will only talk about the ``System V'' style of init that Linux systems mostly use. ... Typically, the first thing it is told to do is to run an initialisation script. The program that executes (or interprets) this script is bash , the same program that gives you a command prompt. In Debian systems, the initialisation script is /etc/init.d/rcS , on Red Hat, /etc/rc.d/rc.sysinit . ... But S10syslog is really a link to /etc/init.d/syslog which is a script to start and stop the system logger. ...

The aurora is only seen in polar or near-polar regions. ... Elsewhere in the tank he mounted an "electron gun" like the one found in TV picture tubes--a hot wire emitting electrons, and plates charged to positive voltages to pull them out and speed them on their way. ... On the other hand, the electrons of the polar rain , which apparently did come from the Sun, were indeed found in patches surrounding the magnetic poles, exactly like the patches of light Birkeland observed on his terrella. ...

Optical Filters . ... In addition to the above complement of broad and narrow-band filters, WFPC2 features a set of three specialized quadrant (quad or Q) filters in which each quadrant corresponds to a facet of the pyramid, and therefore to a distinct camera relay. ... In Table 3.1 and Table 3.2 , each of the type "A" filters is equivalent to inserting 5 mm of quartz in terms of optical path length, with compensation for wavelength such that focus is maintained on the CCDs. ...
