... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...

... arXiv.org . ... Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. Here, we are interested in checking if these new observational imaging constraints can be accounted for by predictions based on existing models of passive centrally irradiated hydrostatic disks made to fit the SEDs of the Herbig Ae stars. ...

... Within SAS, a tool is available to check the pile-up fraction in the pn data: epatplot . This tool compares the observed pattern distributions (derived from a pn calibrated and concatenated even list) with the calibrated models. ... The lower panel is the key element for the evaluation of the pile-up fraction: it shows the observed distribution of pattern as a function of energy (PI channel in Analog-Digital Units ), using the same color code. ...

... In , the visibility amplitudes and phases of the program stars are calibrated using calibrator stars, for which those variables are modeled and the resulting model coefficients transferred to the program star data. ... When calibrating the data, the user should begin by looking at the calibrated and normalized amplitudes first to see whether the data has already been calibrated (for example when a .cha file was read). ... In the case of visibility phases, there are no normalized quantities.) ...

This is how a typical dispersion modeling result looks when shown as a map. ... Their numerical values are shown at the top. White normally means no data, but high values may be also shown as white if above the fixed high limit (that is, if no automatic normalization is used for colors). Note that calculations were done both for cell positions and for station positions, so both are colored. PO territories are filled by color corresponding to the average value of cells overlaying them. ...
