... 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]. ...

... The XMM Optical Monitor can produce data in two modes: Imaging and Fast (timing). The omgchain package reduces the OM Imaging mode data taken with either the UV or Optical grism filters (prism filters with diffraction gratings on the back which facilitate low-resolution spectroscopy). There are two filter positions of the filter wheel in front of the OM detector which are occupied by grisms (hereafter called grism-filters), one designed for the UV spectral range and another for the visual. ...

On 19/20 October 1995 we used GRIM II to attempt spectroscopy of the 2.3 micron CO absorption band in stellar clusters. ... Read Noise Our typical backgrounds in 60s were about 100 DN (about 500 e), and so for faint objects our noise is utterly dominated by the read noise of about 110 e. We can think of three ways to improve this situation: integrate longer; reduce the read noise; or implement multiple reads. ... Flats The quartz lamps were too dim for flats. ...
