Next: Examples of data contained Up: Electronic database Previous: Future plans . In astrophysics, the optical constants mainly are used to calculate the optical properties of scatterers, i.e. cross-sections, scattering matrix, etc. ... Optical properties derived from such models have been discussed in some books (see, e.g., [ 2 , 3 ]) and in principle can be calculated by using various light-scattering tools which are freely available via the internet [ 4 ]. ...

... plots of rms/mean by channel . bandpasses for the individual 25 Mhz bands where the resonances occur . ... A simplified model of the system temperature including these resonances is: Tsys= Tomt*alpha + (1-alpha)*Tsky + Tamp. ... If you are on cold sky then Tsky may be 6+ 14(scattered)=20 K while the OMT temperature is about 100 K. If you look at a 12 jansky source then Tsky= 20+12*10= 140K is greater than Tomt so Tsys will have a negative going bump at the resonance frequency. ...

... When is known, the PSF is known and the numerical procedure is the modification of the Richardson-Lucy iterations (Richardson 1972, Lucy 1974) described by Snyder (1990) and Snyder, Hammoud, and White (1993): . ... When is unknown, the problem is more difficult. ... For this case, the EM algorithm for updating both the object and the aberration parameters becomes, . ... Eq. 15 can be satisfied, for instance, by performing a few iterations of any numerical optimization procedure. rlw@sundog.stsci.edu...

. This animation shows a simplified model of the varying temperature data at yearly intervals. The latitude banding has been smoothed to more clearly show the how Titan's peak temperature moves from 19 degrees south to 16 degrees north latitude between 2004 and 2016. The small globe in the upper right corner shows the view of Titan as seen from the direction of the sun. The latitude on Titan where the sun is directly overhead (the subsolar latitude) is indicated by a yellow star. NASA/JPL-Caltech/GSFC

We present simultaneous ultraviolet and optical observations of five flares on the very late type M dwarf Gl 866 (dM5.5e). A procedure to estimate the physical parameters of the flaring plasma has been developed using a simplified model of the flare and a comparison of observed and computed Balmer decrements. With this procedure we have determined the optical thickness, electron temperature and electron density of the flaring plasma at flare maximum for three spectroscopically observed flares. ...
