9 CORR_RATE counts/sec RATE after
extrapolating (if neccesary) to an aperture radius of 12 unbinned pixels and
correcting for coincidence losses.
10 CORR_RATE_ERR counts/sec
11 CORR_BACKGROUND_RATE counts/sec BACKGROUND_RATE after
extrapolating (if neccesary) to an aperture radius of 12 unbinned pixels and
correcting for coincidence losses.
12 PSF1_CORR percentage Point-spread function
correction applied to extrapolate RATE from measurement aperture area to area
of 12 unbinned pixels
14 NOPIXELS none Number of pixels contained by an
extended source (EFLAG=1). Point-sources (EFLAG=1) will have this value set to zero.
15 APERTURE unbinned pixels For point sources
(EFLAG=0), the aperture radius (unbinned pixels) used in the photometry. For
extended-sources (EFLAG=1) this value will be set to NULL.
16 FWHM_MAJ arcsecs The full-width-at-half-maximum
of the semi-major of the ellipse describing the shape of the source (computed
by moments)
17 FWHM_MIN arcsecs The full-width-at-half-maximum
of the semi-major of the ellipse describing the shape of the source (computed
by moments)
18 PA degrees The postion-angle (referred to
the x-axis)
of the semi-major of the ellipse describing the shape of the source (computed
from moments)
19 QFLAG none (source quality flag) Can be either 0 or 1.
Set to 0 if all the image pixels used to obtain the counts for the source were good, 1 otherwise.
20 CFLAG none (source confusion flag) Can be
either 1, 2, 3 or 4.
1 means that the nearest source is at a distance of greater than twice
the aperture radius.
2 means that there are one or more sources within a distance of twice the
aperture radius, but at a distance greater than the aperture radius.
3 means that there are one or more sources within a distance of the aperture
radius.
4 means that the source lies near an edge of the image
21 EFALG none (source extension flag) Either 0 point-source
(none-extended) or 1 extended.
