... 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. ...

... We conclude with a discussion of the problem of estimating goodnessoffit in the limit of few counts using our modified ь 2 statistic. ... Introduction When fitting models to data with few counts, two of the most common methods used are the standard ь 2 method and the C statistic. ... As Wheaton et al.

We measure highly significant Baldwin effects for most broad emission lines (C IV 1549, C III] 1909, Mg II 2798, H ,H ) and show that they are predominantly caused by correlations with luminosity, not redshift. ...
