Program: TRACE Purpose: TRACE plots image values at user given positions as function of distance to a plot centre (in 2-d (sub)sets). Category: ANALYSIS, PLOTTING File: trace.c Author: M.G.R. Vogelaar Keywords: INSET= Give set (, subset): Only one subset is allowed. ... XYBOX= Give size of box around one pixel: [3,3] The resulting value at a selected position is an average of the pixels in the defined box around that position. ... POSITION= Give position x, y: Physical values are allowed. ...

FSP1 : The time intervals corresponding to the INTERBALL TAIL PROBE (IB_TAIL) or GEOTAIL passage through the simulative magnetosphere boundary layer (BL) . ... FSP3 : That part of the FSP1 or FSP2 time intervals, which corresponds to the magnetic conjugations between any couple of the considered spacecraft. The value of the relative geocentric angular distance between magnetic field line's footprints is considered during FSP3 situation selection. ...

polimodel -- Produce model linear polarization and position angle images . ... Whether to apply random errors to output polarization and position angle values. seed = "" [integer] . ... This task produces a model linear polarization image and corresponding position angle image from an input image assumed to represent intensity (Stokes I parameter). ... A threshold for the input image can be defined such that polarization and position angle are not computed for input values less than this threshold. ...

. Computer Ephemeris. Lunar equatorial positions. Explanations. Each row contains at 0 h and 12 h of Time Dynamical Terrestrial: month, day, apparent right ascension (hours, minutes, seconds), apparent declination (degrees, minutes, seconds of arc) and geocentric distance (in Earth's radii).

... Magnetar In The Sky . ... SGR 1900+14 is believed to be a city-sized , spinning, super-magnetic neutron star, or Magnetar . How strong is a Magnetar's magnetic field? The Earth's magnetic field which deflects compass needles is measured to be about 1 Gauss, the strongest fields sustainable in Earth-based laboratories are about 100,000 Gauss, yet the Magnetar's monster magnetic field is estimated to be 1,000,000,000,000,000 Gauss. ... NASA Official: Jay Norris. ... Earth's North Magnetic Pole . ...

. Mars is "behind" the sun from the earth's point of view and is therefore not visible in the nighttime sky (i.e. its up in the daytime). Venus it at greatest elongation and appears in the western sky as a bright object for 2-3 hours after sunset .

. Next: Initial velocity Up: Space and velocity distributions Previous: Space and velocity distributions . Following Paczynsky (1990), we assume initial space distribution of young neutron stars to be varying exponentially with distance from the Galactic center and from the Galactic plane, that is probability distribution for young neutron star positions can be written in the form . with kpc, and pc.

... The amount of energy encircled by an aperture used for stellar photometry will depend on both the aperture size, and also on any variations in the PSF with field position, time, etc. ... The differences in photometric magnitude between apertures with various radii (i.e. aperture corrections), and their mean and standard deviations for the F555W filter, are presented in Table 5.5 . ... Variations in the PSF with field position will, of course, cause a position dependence in the aperture corrections. ...

The Earth. ... The middle raiding of the Earth is 6371,032 km, the pole 6356,777 km equatorial - 6378,160 km. The Earth surface area is 510,2 mln km^2, 70,8% of which is the World ocean. ... According to the modern cosmogonical views the Earth was formed 4,6 - 4,7 billions years ago from the protoplanet cloud captured by the Sun. ... The Earth is conditionally divided into 3 parts: a bark a cloak and a core (in the centre). The external layer - the bark is 35 km thick. ... Above the Earth. ...
