Dimery And Rogers Funeral Home Obituaries Near Florence School District 1 Sc, 3 for PWV < 0. We used APEX SEPIA Band 5 to observe the 183 GHz H2O line towards 2 Red Supergiant and 3 Asymptotic Giant Branch stars. Aug 17, 2019 · SEPIA contains three channels called SEPIA180 (ESO-OSO PI), SEPIA345 (facility) and SEPIA660 (facility). Based on the technological progress and the experiences gained in building a narrow-band FFTS (Stanko, 2005) the APEX FFTS was developed by the MPIfR Digital Group. The receiver shares the backend with FLASH+ receiver, XFFTS, (PI instrument built by MPIfR, Bonn). We describe the new Swedish-ESO PI Instrument for APEX (SEPIA) receiver, which was designed and built by the Group for Advanced Receiver Development (GARD), at Onsala Space Observatory (OSO) in collaboration with ESO. 5 mm. This happens at about 15% of the total observing time (corresponding to ~50 days per year). We used APEX SEPIA Band 5 (an ALMA Band 5 receiver on the APEX telescope) to observe the 183 GHz H 2 O line towards two Red Supergiant (RSG) and three Asymptotic Giant Branch (AGB) stars. . At APEX, the atmospheric transmission at 183 GHz (water line) is better than 0. Apr 7, 2017 · We investigate the use of 183 GHz H2O masers for characterization of the physical conditions and mass loss process in the circumstellar envelopes of evolved stars. Joining an established suite of instruments attached to the ESO-operated Atacama Pathfinder Experiment (APEX) telescope, the Swedish-ESO PI receiver for APEX, or SEPIA, is now spearheading the search for water in the Universe. In this manuscript, the SEPIA receiver design, the receiver channel per-formance and the commissioning results are described. The APEX FFTS is based on the currently most powerful digitizer/analyzer board available from Acqiris, Switzerland. c9lrh, yyjsw6p, ea, wrl, ijjp, e7ln8x, fo48jhn, obg, d5c2, cgij0j,
