... BARS.BDF . consists, firstly, of three rectangular bars; each of length 25 pixels; of width 1, 4, and 9 pixels; horizontally positioned; and flush with pixel boundaries. The uniform flux density in each pattern is 100 units per pixel. ... In order to illustrate the case of a point spread function which in one dimension is extremely undersampled, a delta function is also included (the lower left hand pattern in BARS). ... Uniform flux density of 100 units/pixel is used. ...

... Figure 1.1 on page 2 also illustrates the projected orientation of the WFPC2 CCDs onto the sky. ... On the CCDs this region appears as a blank "shadow" region along the X~0 and Y~0 edges of each CCD; the exact limits of this region are given in Table 2.5 for each CCD. ... The WFPC2 has two readout formats, namely full single pixel resolution ( FULL Mode), and 2x2 pixel summation ( AREA Mode which is obtained by specifying the optional parameter SUM=2x2 as described in the Proposal Instructions). ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

... Coordinate system . It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ... The TCC rotator angle (object system) is defined to be 0 degrees for this orientation. ... Thus, the rotator angle gives the conventional astronomical position angle on the sky of the y axis (although Russell won't acknowledge this necessarily). ...

... satvelsrc computes as a function of time the component of the spacecraft velocity vector in the direction of given celestial source. ... SAS_ODF . or named via the generic command line parameters -o or -odfdir (see taskmain for details). ... The source coordinates obtained from the ODF can be overridden with the command line paramters withsrccoord=yes srcra=<ra> srcdec=<dec> and withorthosrc=yes defines a fictitious source in the direction perpendicular to the orbital plane. ...

Intensity of atmospheric motions in the mabl retrieved from ocean surface radar imagery M. Mityagina E-mail: mityag@iki.rssi.ru Abstract. The paper is dedicated to the theory and practice of analysis of radar images of sea surface, obtained under unstable atmospheres. In this case, the sea surface reveals wind field variations in the marine atmospheric boundary layer (MABL) caused by atmospheric convec-tive processes, accompanied by air motions with mainly vertical direction. ...

Program: ANTPAT Purpose: Calculate beam width (Full Widths at Half Maximum) and position angle of synthesized beam. ... BOX= Give box in ..... [entire subset] The data enclosed by this box will be used to estimate the beam parameters: Full Width At Half Maximum (FWHM) of major axis, FWHM of minor axis and the position angle Only the data within the box that belong to the first maximum of the antenna pattern with a value greater than or equal to CLIP= will be used in the calculations. ...

spaceweb@oulu.fi - last update: 21 December 1998, 1400 UT (RR) . ... This is not as trivial a question as one might think, since it is not enough to know the location with respect to the Earth and/or the Sun in some arbitrary coordinate system. One may have to consider things like differences between the solar equatorial plane and the Earth's orbital plane, the changing direction of Earth's spin axis during the year, and the magnetic dipole orientation. ... Geocentric solar ecliptic . ...

Coordinate Systems used for spacecraft trajectory description: . ... The HGI coordinates are Sun centered and inertially fixed with respect to an X-axis directed along the intersection line of the ecliptic and solar equatorial planes. ... Cometocentric (solar) Ecliptic Coordinate System (CSE) . ... CSE coordinate system for the SC POSITION: axis origin at comet center, X-axis to the SUN, Z-axis to ecliptic north pole, (X,Y)-plane is parallel to the ecliptic plane. ...

When feed is rotated over the tertiary: . ... z is toward the tertiary from the focus position . ... angle : Center of rotation is about the optical axis. range 0 to 360 degrees (minus a few degrees for the limits) . ... CW when sitting on the tertiary looking up at the dipoles. radius : moves in the x,y plane along the direction that the angle currently points . ... Dipole positions : . ...
