High time resolution bin-mode observations

Miriad's atlod task has an option, options=hires which converts a RPFITS file observed in high time resolution bin-mode into an apparently normal dataset with fine time resolution. You should note the following caveats:

• Although the timestamp of each correlation reflects the observing time of that correlation, the u-v-w coordinate is that for the midpoint of the correlator cycle (i.e. the u-v-w coordinate is not recomputed at the high time resolution).
• Certain Miriad tasks that need to detect the end of an integration do this by checking whether consecutive timestamps differ by some tolerance. In high resolution time mode, the time difference between consecutive integrations might be smaller than this tolerance. There may be some resulting confusion.
