HET target acquisition statistics
Target acquisition statistics
Monthly average statistics for how long it
takes to acquire targets and their accuracy
The above graph shows the monthly averages per instrument over the
past few years.
  
The panels above show the average setup times broken down by
SetupMethod on each instrument.
Note that starting in 2019 we separate setups on each instrument by
the requested SetupMethod; previously we separated only by
instrument.
The table below contains the full dataset of setup times:
