Hi
Im trying to download the science image, reference image and difference image for one transient event via lasair-ztf.lsst.ac.uk/ … if i click on the alert packet data button it mentions a file location. can i download this? for a particular event of interest, if i click the target, ref or diff image in the ‘images’ column, i dont get anything coming up…
many thanks
Gav

Gavin – Can you try the “Go deeper” button? See the red arrows in the images below – Roy

thanks roy.

that gives the latest image but not – as far as i can see – images in the past.

using the AlecRCE ZTF viewer i can get the images for events. but i haven’t worked out how to see non-detections. for instance for the source in question, there is a g band detection but a non detection in r at basically the same time.

any thoughts welcome.

all best
Gav
