... For the XRBs which are highly variable the concurrent presence of the RXTE/ASM that continuously measures their X-ray spectral states invites a new and innovative program to harness the available information to facilitate detailed studies of individual systems as well as comparative studies between classes of systems. ... This will enable them to quickly decide which data are worth putting in effort to extract and further analyze. ...

The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).

At Arecibo we have a variety of optical instruments that we use to study terrestrial airglow emissions. ... As a complement to the airglow instrumentation we also maintain a set of optical instruments, called lidars, used for "active" remote sensing of the atmosphere. That is, we generate our own source signal using lasers and measure the characteristics of the light scattered back from the atmosphere. ... An operations manual for the Optical Laboratories is currently under major revision. ...
