Heat maps with each pixel showing the average merger time of when it is occluded from ResNet50, Swin, CNN, and autoencoder as labelled by the column title. Each heat-map is colour scaled individually, where dark colours indicate an earlier time and light colours indicate a later time. True time is shown as red line in the colour bar while the un-occluded predicted time is shown as a yellow line. Original galaxy is shown on the left of each row as u, g, and r band composite with each channel individually arcsinh scaled twice and then normalised between 0 and 1. The true normalised merger time is shown in the left panel of each galaxy while the predicted normalised time is shown in each networks’ heat-map.
