WebAperture photometry consists of two parts: summing of pixel counts in a circular area, also known as an aperture, centred on a point source (a star, an asteriod, or a supernova), and; subtracting the excess unwanted pixels that are contributed from sources behind and in front of the object. The excess pixels in (2) are also known as sky or ... WebApr 3, 2024 · In aperture photometry A set of pixels in the image are chosen and we sum those to produce a single flux value. The SPOC produces an optimal aperture, which is used by default in Lightkurve, and determined by the data processing pipeline.
