The above files are the full images URL; You can find these and the delta file names manually by looking in the index.json files on https://system-image.ubuntu.com/ for the relevant channel, in our case here exatly in http://system-image.ubuntu.com/ubuntu-touch/stable/bq-aquaris.en/krillin/index.json (at the end, while writing this the delta between r24 and r25)
the r24-r25 delta files are:
