The first step in commissioning UNSWIRF was to calibrate the relationship between etalon spacing d and peak transmitted wavelength . ... Thus, UNSWIRF is virtually monochromatic, and can in principle be used as a pure tunable line imaging filter, provided velocity gradients and dispersions are small (<50б km ), and the line centre wavelength is known in...

... Based on fX / fO , LX , X-ray spectral hardness, and optical emission-line diagnostics, we have conservatively classified 36 normal galaxies and 71 AGNs. ... 2004). ... In x 3 we discuss normal galaxies in terms of their LX /LB evolution, log (N )-log (S ) relation, and X-ray luminosity function. ... Therefore, to further separate AGNs from normal galaxies, we use several diagnostics: the X-ray luminosity, X-ray to optical flux ratio, X-ray spectral hardness, and optical line ratios. ...
