Automatic Detection of NEOs in CCD Frames . ... CCD frames obtained with modern telescopes with robotic operation allow carrying out standard observation programs for detection of peculiar objects on stellar backgrounds, as is the case of Near Earth Objects (NEOs). ... In this paper, we present original algorithms for automatically detecting dim NEO images in telescope frames, considering both sidereal and differential tracking [2]. ...

... The distomats measure the average height of the platform every 2 minutes. If the average platform height is more than .04 inches from the nominal position, the tiedowns will pull (or release) equally on all 3 corners to bring the average height back to the nominal position. ... The platform corner height versus dome position (at fixed average platform height) shows that the platform corners move by +/- 6 inches just from the dome motion (this was before the alfa upgrade). ...

... Another significant contribution to the crystal energy of metals is the electron-ion interaction or the electron bandstructure energy (E BS ) which is defined by the interaction of valence electrons and the Brillouin zone (BZ) planes. ...

The overall efficiency (including atmospheric transmission, reflectivity of the telescope mirrors and overall efficiency of the optics and of the detector) for broad-band imaging should be about 25% in H and K, and about 15% in J. The main noise source for both broad- and narrow-band imaging should be the photon noise associated to the background+source flux. ... Flat fielding (and possibly background subtraction) might increase the noise by a factor 2 ? ...
