... I slept on my image of SN1999cq and decided to revisit my initial analysis, using "Submarine Sonar Subjective Analysis Techniques" (or whatever that means for - e.g. do we have a target or not ?) ... 1) LEHMANN's Image is great and matches Circular# 7209. ... 3) KERESZTY-ZOLT's Image shows only the very slightest hint for resolution of SN1999cq, in the generally diffused central area of UGX11268. 99.9% of what is marked as the ID for the supernova is actually the upper object shown in LEHMANN's...

... 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). ...

Detection technique . We are using ISIS , the optimal image subtraction method developed by C. Alard & R.H. Lupton, to search for SNe in our images. ... The second image shows the same subtraction, but after the convolution of the best image with ISIS: . ... For this reason, we are suggested to search for nuclear SNe with NICMOS on HST, to exploit its stable PSF, sensitivity and angular resolution to detect from space nuclear obscured SNe which might have been missed by ground-based surveys. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... Previous attempts to match the SDSS plug-plates to the surface of best focus were conducted using only the bending fixture. The analyses performed indicated that by adding a central constraint to the plug-plate deformation process, the plates could be made to match the surface of best focus within an acceptable range of error. ...

The merging galaxy Arp 220 is the prototypical luminous infrared galaxy. ... In 1996, one of the then largest VLBI experiments was conducted on Arp 220, using the compact OH maser peak as a convenient phase reference. This permitted continuum imaging of the galaxy with high sensitivity, revealing the existence of roughly a dozen unresolved sub-mJy point sources scattered across the nuclear region of the galaxy. ... The nuclear region of Arp 220 imaged with continuum VLBI at 18 cm. ...
