To anyone who was inconvenienced by my posting the GIFs of the ultrasonic
schematics: my apologies. I posted them because of the large number of
requests I received from other members of the list.

Perhaps a more constructive way to respond to this issue would be to define
what is "too large" a file to attach (or if one should attach files at
all).

I shall be guided by the collective opinion.
