... The DiFX correlator has a capability to process many phase centers within a primary beam in one pass. ... SCHED supports the multiple phase center mode by providing the details of all the desired phase centers to use for a given pointing center in the output .v2d file, which is used in correlator setup. ... When using this capability, the user should specify the size of the FFTs to do on each baseband channel before spliting the data for each phase center. ...

... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...

Danielson and Kalocsa craters in the Arabia Terra region of Mars were imaged during orbit June 19, 2011, by ESAтАЩs Mars Express High-Resolution Stereo Camera (HRSC). Centered at around 7€ђN and 353€ђE, this anaglyph 3D image has a ground resolution of about 26m per pixel. Data from HRSCтАЩs nadir channel and one stereo channel are combined to produce this 3D image that can be viewed using stereoscopic glasses with redтАУgreen or redтАУblue filters. ...
