MESSIER 5 AND ITS VARIABLES `A noble mass, refreshing to the senses after searching for faint objects' Admiral Smyth The oldest known stars have survived chiefly in the rich and wonderfully symmetric formations called globular star clusters. ... 2] Charles Messier revealed the globular cluster on May 23, 1764. ... The globular cluster itself is magnificient and granular at 60x. Individual small stars are scattered around the edges, and one or two of them can exceed the others in brightness. ...

We start with an observation for which the PRF is much worse than it should be; caused by residual wobble errors or other causes. ... Spatial analysis of ROSAT HRI observations are often plagued by poor aspect solutions, precluding the attainment of the potential resolution of about 5''. ... A recent example showed one obi for which the source was 10 north of its position in the other 17 obis. ...
... Basic algorithms for the production of stellar photometry from CCD observations are described and reviewed. ... The problem of doing accurate stellar photometry with calibrated charge-coupled device (CCD) data amounts to that of condensing the intensity values of hundreds, thousands, or even millions of picture elements (pixels) into a list containing the magnitude and position of each star on the CCD image. ... Center an aperture of N A pixels on the star. ... PIXEL.LT.PEAKMAX)) THEN BINGO = .TRUE....

... The telluric features redward of 6700 A have been removed from the accurate spectro photometric standards of Hamuy et al. to permit more reliable relative and absolute spectrophotometry to be obtained from CCD spectra. Smooth яuxes from 3300 to 10500 A are best determined by dividing the raw spectra of all objects taken in a night by the raw spectrum of a "" smooth оо spectrum star before deriving the instrumental response function using the revised standard star яuxes. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
