counts and rate are bgd.-subtracted, based on simple spatial fitting (if done) or extracted counts from aperture otherwise (N.B., in either case aperture counts are given csv file).
cntserr, rateerr = Error on (source) counts and count rate, based on error in total counts
SNR = signal-to-noise ratio, computed using Nsrc/sqrt(Nbgd)
poisprob = Poisson probability of observing total counts given bgd. counts
sigmaj, sigmin = source extent (from detection output or spatial fitting) in units of arcsecs.
incang = position angle of source (inclination from x-axis)
cnts_soft = bgd.-subtracted counts in soft band (0.50 - 2.00 KeV, always taken directly from source aperture rather than model fitting)
cnts_hard = bgd.-subtracted counts in hard band (2.00 - 7.99 KeV, always taken directly from source aperture rather than model fitting)
hr, hr_err = hardness ratio ([cnts_hard-cnts_soft]/[cnts_hard+cnts_soft]) and error
ext = source extension flag: F = false (not extended), T = true (extended), A = asymetric (ratio of sigmaj/sigmin > 1 + x, where x = 0.5 by default)
var = variability flag: U = unknown, F = false (is not variable), T = true
N_H = Galactic column density as determined from LHEASOFT nh program
flux = flux determined from count rate using pimms (in the 0.30-8.00 keV bandpass for a power-law model with ph. index = 1.8)
vign = vignetting correction
Flags: d = detection parameters, s = simple spatial fitting parameters,
b = simple spatial fitting failed, p = poor simple spatial fit, x = extracted events parameters, t = temporal anaylsis parameters,
i = psf spatial fitting parameters, f = spectral fitting parameters,
c = source is confused, u = user-defined source, v = detected source coincident with user-defined source, r = source is in region-of-interest
