... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

... III (OCR by CDS, corrections by H.Andernach) The first results of a search at 1410 MHz for 243 extragalactic objects from the Southern Hemisphere identified as quasars by Veron-Cetty Veron (1983) in "A Catalogue of extragalactic Radio-Source Identifications" are reported. ... The data are from Parkes catalogue . ... These data were modified using 'A catalogue of Quasars and Active Nuclei (2nd Ed.)'

... 2015 . ... Observations using the Arecibo S-band (2380 MHz, 12.6 cm) planetary radar system started in 1976 and its power and sensitivity were greatly improved with the telescope upgrade and Gregorian-dome installation in the mid-1990s. Below, we show the number of near-Earth asteroids attempted and detected since the radar program resumed in 1998. ... The number of NHATS objects detected with Arecibo similarly jumped in 2012, and 2015 was again a record year, where we detected 23 of these objects. ...
