CARMA CGS (Correlator Graphical Setup) Publisher's description
Correlator Graphical Setup is a tool that let's you visualize CARMA correlator bands in frequency space and see the spectral lines that you want to observe.
Correlator Graphical Setup is a tool that let's you visualize CARMA correlator bands in frequency space and see the spectral lines that you want to observe. Once you have the setup you like, you can click to get the Python setup commands to paste into your observing script. You can run it from your browser with Java Webstart or download the applicate JAR file and run it from the command line.
What's New in This Release:В· Additional velocity information displayed at the bottom of the center information box. Band are labelled by number. New and improved presets. New CARMA-23, DUALPOL, and FULLPOL modes (currently in state of flux). Improved help text. Additional minor bug fixes.
Note for high-z sources:
В· The CARMA control system does not currently do a full relativistic Doppler correction (see discussion in CARMA Bug #334). The current calculation is accurate to about a part in 10**9. The magnitude of the error is linear in velocity. For example, for an earth velocity of 25 km/sec along the line of sight to the source, a source velocity of 10000 km/sec and an observing frequency of 100GHz, the error in the sky frequency is 280 KHz.
В· What this means is that you should set up CGS using the source velocity (or Z) so that the tuning restfreq is redshifted - but make sure your catalog has VLSR=0 for the source.
В· Number of channels and available BW modes consistent with CARMA offerings
В· Improved Doppler shift fu...
