... Based on AIPS, and developed under Solaris and IRIX, NEWSTAR has been expanded to include LINUX and HP-UX versions that have considerably improved the reduction performance of NRO observational data. ... Since NEWSTAR was originally developed for data reduction within NRO on Solaris, Sun and IRIX platforms, users wanting offsite access to NEWSTAR formerly had to obtain computers similar to those at NRO or access NRO machines remotely. ... Development of Radio Reduction Software NEWSTAR 523 Figure 1....

... Subject headings: ISM: molecules --- line: identification --- molecular data --- molecular processes --- radio lines: ISM We recently detected the radio spectrum of the negative ion C 6 H # in the laboratory and showed that this suprisingly large carbon chain anion is the carrier of the unidentified harmonic sequence of molecular lines B1377 observed by Kawaguchi et al. (1995) in the circumstellar shell of the carbon star IRC #10216 (McCarthy et al. ...

Arcetri Observatory, together with MECSA, have developed a sample/hold curcuit and a demultiplexer for the ALMA sampler unit. ... The S/H circuit requires a 4 GHz sinusoidal clock (0 dBm nominal), and has an internal clipping circuit to protect the input from signal spikes. ... A custom chip has therefore to be designed. ... The chip requires two sinusoidal clocks, at 4 and 0.5 GHz. ... G. Collodi, G. Comoretto: A MMIC sampler for ALMA - Design report - Arcetri technical report n. 2/2001 . ...
