Comparing the summed map with the maps from the individual energy ranges, the one which produced the smallest error box was chosen to represent the source position, as long as was greater than 4, a level chosen to reflect a reasonable degree of confidence in the detection. ...

... Meta Index / Home Page / Description The statistic for optimizing the match between optical and X-ray sources is: . ... with the distance between an X-ray (i) and an optical source (j), the associated error and resp. the number of X-ray sources and optical sources in the list. ... Of course, in practice there will be chance coincidences. For chance coincidences the chance that an optical counter part will be within a distance from the source is (i.e. within an error circle of ). ...

We describe all the steps of the standard reduction including per pixel error propagation: Bias correction, treatment of bad pixels, flatfielding, and filtering of cosmic ray events. ... We build difference images via image convolution with a technique called OIS (optimal image subtraction, Alard & Lupton 1998), proceed with PSF-fitting, relative photometry on all pixels and finally apply an automatic detection of variable sources. ...

... It is found that the metallisity distribution of disk stars has a gap which subdivide the disk population into two groups. The distribution may be described by the sum of two normal curves which are centered at [Fe/H]=-0.22 and +0.08. The curves can be interpreted as distributions of random errors in metallisity of sample stars. This leads to the conclusion that all stars in each group have actually the same value of [Fe/H]. ...
