This is enough to harm phasing of the VLA at high frequencies and enough to be rather undesirable for positions used on the correlator. ... For example, the B1950 coordinates of the VLA calibrators are either based on absolute measurements made in 1979.9, or are converted from more modern J2000 coordinates using an assumed ``observe'' date of 1979.9....

While the ordinary, daily fibre flats mainly measure fibre characteristics, the image flats are exposures of the CCD by the flat field lamp without the fibre system. ... Two kinds of small-scale fluctuations exist in any raw frame: photon noise, and fixed-pattern (gain) noise (the third source, read noise, is negligible here). ... The penalty to pay is added photon noise, inherent in the image flats. ...

... spectrum . ... The photons we detect originate in the outermost layers, or atmosphere, of the star. In order to interpret stellar spectra, it is necessary to construct models which accurately represent the structure of a stellar atmosphere and the transfer of radiation from the stellar interior into interstellar space. For the study of helium stars and other stellar remnants, we in Armagh use several computer programs, of which sterne and spectrum are the most important. sterne . ...
