1. GRB080319B
. Images of the position of GRB080319B before the burst (left) and at the moment of maximal optical brightness (right). The transient position is marked with an arrow. Peak optical brightness made the burst visible by a naked human eye (5.3 stellar magnitude). To view high temporal resolution video of the transient seen by TORTORA camera, click here (avi).

2. Optical Distortion
The WFPC2 cameras have significant geometric distortion which not only affects astrometry, but also affects photometry (because it induces an apparent variation in surface brightness across the field, and hence impacts the flat fields). ... The pixel scale can be estimated from the commanded offsets between the frames (relying on the FGS scale and distortion calibrations). ... The cubic distortion coefficients can be used to derive effective pixel areas as presented in Figure 5.16 . ...

... 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]. ...

7. RBSC-NVSS SAMPLE. I. RADIO AND OPTICAL IDENTIFICATIONS
... astro-ph/0003002 We cross-identified the ROSAT Bright Source Catalog (RBSC) and the NRAO VLA Sky Survey (NVSS) to construct the RBSC-NVSS sample of the brightest X-ray sources (~0.1 counts s^{-1} ~= 10^{-12} ergs cm^-2s^-1 in the 0.1--2.4 keV band) that are also radio sources (S ~= 2.5 mJy at 1.4 GHz) in the 7.8 sr of extragalactic sky with |b| > 15deg and DEC > -40deg. ... We used the more accurate radio positions to make reliable X-ray/radio/optical identifications down to the POSS plate limits. ...

15. ADASS 2002 Conference Proceedings
... Using a simple 2-D Gaussian Point Spread Function (PSF) on a constant (flat) sky background, I derive a theoretical photometric and astrometric performance model for analytical and digital PSF-fitting stellar photometry. ... The photometric performance is maximized when either the effective background area or the effective-background-level measurement error is minimized. ... An important, but frequently ignored, noise source is the uncertainty of the measurement of the effective background level ( )...
