Radio Telescopes 'Save the Day,' Produce Data on Titan's Winds

If I'm not mistaken, the only data that was initially lost was the
wind doppler information. All the other data was broadcast on two
different channels.
Alas, not so. Some of it was simply duplicated across the two channels,
but the camera in particular sent different images on channels A and B
rather than duplicating them.
Any hope that they can recover the missing images? Or is the
signal to noise not good enough?
For the ground-based telescopes, to get good Doppler
resolution, they normally work narrow band and only
measure the carrier. Modulation would be noise in
this context. I know bandwidths of less than 1Hz are
available though I don't know what was used in this
case. The narrower the bandwidth, the better the SNR.
