Aperture photometry of moving asteroid

[AstroT]

Hi all --- me and students are wondering if AIJ has the functionality of letting a given aperture follow a moving object like an asteroid across the FoV in an automatic manner? Right now we have 100s of images and need to do the aperture photometry by hand for each image. Would be nice if that is possible.

Do you have an example calibrated image time series that you'd be willing to share with us to use for testing?

Dear Karen,

thank you for your reply. Sure, I am attaching three FITS files. If you blink between them you will quickly identify the asteroid. Best wishes, Toby

Do you have a sequence with more images (say >10)?

Also, our plan is to have the user identify the moving object in the first image using a mouse click and then identify the object in the last image. Multi-aperture would then assume the movement in RA/Dec is constant (in time) over the time-series for the purposes of placing the moving object aperture in the intermediate images (or if WCS coordinates are not available, it will assume movement in x,y is constant). Would this methodology work for your application?
