Recently, I came across this software (
https://www.mirametrics.com) and in this link (
https://www.mirametrics.com/news_hd149026.php#results) the authors report the detection of the dimming of a transiting planet. One of the key features, in the opinion of those who performed the data extraction, was the ability of using elliptical apertures to extract photometry. Maybe this feature can be implemented into AIJ at some point?
