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.
