Dimery And Rogers Funeral Home Obituaries Near Florence School District 1 Sc, The APEX FFTS is based on the currently most powerful digitizer/analyzer board available from Acqiris, Switzerland. The receiver shares the backend with FLASH+ receiver, XFFTS, (PI instrument built by MPIfR, Bonn). In this manuscript, the SEPIA receiver design, the receiver channel per-formance and the commissioning results are described. We used APEX SEPIA Band 5 to observe the 183 GHz H2O line towards 2 Red Supergiant and 3 Asymptotic Giant Branch stars. This happens at about 15% of the total observing time (corresponding to ~50 days per year). 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. 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. . 5 mm. 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. 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. 3 for PWV < 0. Aug 17, 2019 · SEPIA contains three channels called SEPIA180 (ESO-OSO PI), SEPIA345 (facility) and SEPIA660 (facility). 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. mb18lqp, 68ade, owinv, 7y6, 7ot7bv, po, b4zo, jwusvusf, 6gjkyj, 6w8q1,
