... ROTATION CURVE: When studying spiral galaxies it is invariably found that the stellar rotational velocity in the disk remains constant, or "flat", with increasing distance away from the galactic center. ... The rotation speed of the stars in galaxies is found NOT to decrease with increasing distance from the galactic center (see emission lines in the spectrum), implying that the overall mass distribution of the galaxy is different from the light distribution. ...

... Calibration and analysis of this observation posed very interesting challenges for the authors, in particular dealing with an exciting new instrument whose on-orbit calibration was not yet well defined. ... Five mosaic positions were observed during five consecutive orbits as well as observations for dark and flat calibration. ... Darks and flats had to be created from contemporaneous reference observations and problems within the calibration process had to be resolved. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes.
