Special Time notes:

Note A: ARASE - This is a spacecraft working group request to support the
ARASE/ERG mission. The radars highlighted in the square brackets for each
interval should run either interleaved_normalscan (a full scan of at least
16 beams with a non-sequential manner that interleaves the beam number,
with a scan time of 1-min) or themisscan according to the mode listed in
the curly brackets. All other radars should run a 'normal' 1-min common
time mode e.g., normalscan. Footprint plots can be found at
