| Abstract: |
The IRAM software for the Plateau de Bure interferometer is based on the GILDAS environment, developed jointly between Observatoire de Grenoble and IRAM. In this environment, several new facilities have been implemented. The calibration program, CLIC, developped by R. Lucas, now provides an automated calibration pipeline, which includes dual-frequency phase calibration and atmospheric phase compensation based on water vapor sounding. On the imaging side, data processing has been oriented towards spectral line imaging and deconvolution tools optimized for limited UV coverage. Besides ``classic'' implementations of the various CLEAN-based deconvolution methods (Hogbom, Clark, Steer Dewdney & Ito, Multi-Resolution), the recently developped WIPE method (Lannes et al) has been implemented. This method provides an estimate of noise amplification due to non-linearity in the deconvolution process and of the deconvolution errors. A CLEAN-based deconvolution method for mosaics has also been developped (see Gueth, this symposium), together with the appropriate tools for short-spacing information from the 30-m. |
