Mount a short whip antenna (from our antenna set box) at the center of the control room patio. a small 3 foot high table was placed at the center of the control room patio (where the concrete scribe marks cross). ... A 327 Mhz signal from a synthesizer locked to the station clock was used to drive the whip. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

... The first step is to open and inspect the camera body. ... Notice that there are snap locks on both sides of the camera body, one of which should already be open since it contained the film removed by the developer. To open the camera body, peel back some of the yellow sticker identifying the camera as KODAK on the top and bottom of the camera and unsnap the plastic pieces. ... You should now have four pieces: the front cover, back cover, middle (main camera with lens), and a cylindrical spool. ...

The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...

... F. A. Primini, and H. E. Payne, eds. SVDFIT: An IRAF Task for Eigenvector Sky Subtraction Douglas J. Mink and Michael J. Kurtz Harvard-Smithsonian Center for Astrophysics Abstract. ... The technique is based on the iterative subtraction of continuum estimates and eigenvector sky models derived from singular value decompositions of sky spectra and sky spectra residuals. ... A subset of these eigenvectors is then fit to the ob ject+sky spectra and the fit removed, leaving residual ob ject spectra. ...

... If two or more spectra have been taken under the same conditions, a very efficient way of removing particle hits from the raw data is to replace pixel values with large deviations from other observations with a local estimator, as done in the command COMBINE/LONG . If multiple images are not available, cosmic ray hits have to be filtered out by a different method. ... where subframe defines the region to filter. ... This step is done twice to remove the hits on the sky on each side of the object. ...

. 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.

Instrument Science Report WFC3 2006-04 Replacing the F093W Filter with the F140W Thomas M. Brown & Sylvia Baggett Sep 25, 2006 ABSTRACT The filter set of the WFC3 IR channel has until now included a filter with significant transmission in the optical, the F093W. The bandpass provided by that filter will extend well below 800 nm when the current IR flight detector (FPA64) is replaced by one with its substrate removed. ...
