real | 4 | ADU | PHOT_INTENSITY_ADU | |
| These are a series of different radii soft-edged apertures designed to adequately sample the curve-of-growth of the majority of images and to provide fixed-sized aperture fluxes for all images. The scale size for these apertures is selected by defining a scale radius ≈<FWHM> for site+instrument. In the case of WFCAM this "core" radius (rcore) has been fixed at 1.0 arcsec for convenience in inter-comparison with other datasets. A 1.0 arcsec radius is equivalent to 2.5 pixels for non-interleaved data, 5.0 pixels for 2×2 interleaved data, and 7.5 pixels for 3×3 interleaved data. In ≈1 arcsec seeing an rcore-radius aperture contains roughly 2/3 of the total flux of stellar images. [In general the rcore parameter is user specifiable and hence is recorded in the output catalogue FITS header.] The aperture fluxes are sky-corrected integrals (summations) with a soft-edge (ie. pro-rata flux division for boundary pixels). However, for overlapping images they are more subtle than this since they are in practice simultaneously fitted top-hat functions, to minimise the effects of crowding. Images external to the blend are also flagged and not included in the large radius summations. Extras for generalised galaxy photometry further spaced in radius to ensure reasonable sampling further out. Note these are all corrected for pixels from overlapping neighbouring images. The aperture fluxes can be combined with later-derived aperture corrections for general purpose photometry and together with pHeight (the peak flux) give a simple curve-of-growth measurement which forms the basis of the morphological classification scheme. | ||||||||

| Number of pixels above a series of threshold levels relative to local sky. Levels are set at T, 2T, 4T, 8T … 128T where T is the threshold. These can be thought of as a sort of poor man's radial profile. Note that for now deblended, ie. overlapping images, only the first areal profile is computed and the rest are set to -1 flagging the difficulty of computing accurate profiles. For blended images this parameter is used to flag the start of the sequence of the deblended components by setting the first in the sequence to 0. | ||||||||
