| Description: | Not a very spectacular image here, but nevertheless a significant point in time, rewarding the efforts of a wonderful team of people who modified the receiver "W" C band channel into a (dual polarization) B band channel. This is a JCMT receiver that will be used within the framework of the eSMA interferometry project, linking the JCMT with the SMA and CSO radiotelescopes on Mauna Kea, Hawaii, see earlier daily images. The receiver was retrofitted within a very short time and produced this spectrum during its very first spectral pointing measurement on the telescope. Minutes earlier, a continuum pointing on Venus was successful on the first attempt. The image shows the CO(J=3-2) emission line at ~345GHz on the point source CRL618, a protoplanetary nebula, with the line at the correct strength. The eSMA project is an initiative of NWO, Leiden University, Jive, ASTRON, and of course SMA, CSO and JCMT. MRAO and SRON also played a role in modifying the receiver. |
