    11This ProtocolZero query is much like [[rf]], except that it is designed for large-scale image acquisition. Normal [[rf]] returns only one sample per command, and thus a user attempting to get a large number of samples by sending many queries to it at a variety of angles suffers poor performance and risks overflowing the Quagent's command queue. [[rb]] improves upon rf by allowing the user to specify a region of samples with only a single command. High-resolution data can take some time to write: the game will appear to hang while it does. On machine "e33" in the lab, this command can acquire about 250,000 samples per second (so, for example, it takes 2 seconds to get a 720 by 720 area).

    3 It is useful to think of [[rb]] as returning a band-interleaved raster. (An image interpretation of such a raster is shown below.)
     3It is useful to think of [[rb]] as returning a raster of duples. (An image interpretation of such a raster is shown below.)
