... Meta Index / Home Page / Photometry Methods Aperture photometry is conducted in a similar fashion to that for the Imaging mode . Because of the very small window, an IMAGING mode window containing the source can be used, through the parameter backgroundimageset , to obtain the background. In this case the source counts will be extracted using the image, whilst the background will be obtained using an annulus centred on the source in the background image. ...
