... To save time, I will only provide ephemerides in 2000 coordinates. ... Note: most the orbital elements used to create these ephemerides were obtained from the International Astronomical Union Circulars (IAUCs), Minor Planet Circulars (MPCs) or the ICQ Comet Handbook. ... The following 1-day ephemeris (March 1, 1997 - October 1, 1997) is from Donald Yeomans of JPL and is based on Reference Orbit #55 (March 4, 1997). 2000 coordinates (March - September, 1997) [3/4/97] . ...

... We revised topographical data obtained for the region to construct a generalized structure of the SPA basin as ringed formation. ... Because of our previous analysis of the ring structure [5, 6] we assumed the projection center o o coordinates as 180 W and 40 S. The hypsografic map shown in Fig. 1 demonstrates a hemisphere of the Moon which contains the SPA basin structure and its environs. ... Then we find the o o basin outermost ring center at roughly 180 and 40 S. Inner structure of the SPA basin...

... The generalized aperture program is designed to simulate the effects on the incident photon stream of physical obstructions, such as thermal baffles and pre- and post-collimators. ... The philosophy behind the aperture program is that a geometrically complicated aperture may be modeled by a combination of geometrically simpler apertures. ... The generalized aperture program takes a list of assemblies and apertures created by the front end, and compares each input photon to the apertures, in turn. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...
