Several times, I found myself wondering if Hoagland is just making stuff up. ...

... For a subsample of seven objects, based on 2MASS NIR photometric colours, a 'photometric' spectral type is determined and compared to the results of the optical spectroscopy. ... We find that two dwarfs show the presence of magnetic activity over long periods, LP 326-21 quasi-constant-like, and 2MASS J17071830+6439331 variable. ... The most common characteristic of magnetic activity in cool dwarf stars is seen in chromospheric lines such as Ca ii H and K and H or as coronal X-ray emission. ...
... Oke (AJ, 99, 1621, 1990) has provided absolute spectral energy distributions covering the wavelength range 3200 to 9200A in AB magnitudes for 25 stars. ... The reduced magnitudes are tabulated at 1A intervals from 3300 to 4700A and at 2A intervals from 4700 to 9200A. Comparison of the fluxes with those determined elsewhere showed that Oke's absolute magnitudes are systematically brighter by 0.04 mag. The magnitudes and fluxes plotted have been corrected for this effect. ...

... 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. ...

... Using a simple 2-D Gaussian Point Spread Function (PSF) on a constant (flat) sky background, I derive a theoretical photometric and astrometric performance model for analytical and digital PSF-fitting stellar photometry. ... The total variance of the stellar intensity measurement of over-sampled stars is thus 2 SE 2 SE :bright + 2 SE 2 :faint = SE + rms SE + BE + 2 RON . ... By symmetry, the variance of the stellar y position measurement of bright over-sampled stars is the same. ...

This could be considered an underestimate, because QSOs are easier to identify than early-type galaxies which appear to dominate the red sample so the 14 objects with unidentified spectra are most likely to be galaxies.) ...
