... Practically all kinds of astronomical images, containing a number of stars and/or galaxies, can be treated with the INVENTORY commands. Up to now INVENTORY has been used or tested on data from the following instruments: Schmidt plates, CCD--frames taken with several telescopes, direct unaided and electronographic plates taken with the ESO 3.6m telescope. ... If one has a number of frames each containing 20 or even a smaller number of objects, it is still worthwhile to use INVENTORY . ...

... About the Sky Map Online, professional edition . The professional version of the Sky Map Online was reflected as the tool for amateure astronomers and for professional astronomers It provides the creation of maps with the magnitude limit for stars up to 21-st magnitude (limit of the First POSS) and field size from several arcmins to 80 by 60 degrees, what makes possible to use it for the following goals: . ... Guiding stars selection. ... Such objects are not recommended to use as guiding stars. ...

... Bojan Nikolic web pages (r. 329) . ... Using high-resolution three-dimensional realisations of turbulent fields, we investigate the limits on achievable performance of atmospheric phase correction using water-vapour radiometers arising from following effects: the incoherent measurement of power from water by the radiometers (in contrast to coherent detection of the astronomical signal); the different tapers of the response patterns of the astronomical and radiometer receivers; and, the ...
