Quick Look Mode
Invoking ECHOMOP tasks with the TUNE_QUICK=Y parameter will cause the
automatic setting of parameters to values to minimise CPU usage.
The following algorithmic optimisation will be used:
- order tracing will use centre-of-gravity to locate the centre
of the order.
- maximum of 200 trace sample points per order will be measured.
- criteria for clipping points from the trace fit will be set
at 1 pixel maximum deviation, and up to 5 pixels may be clipped
per iteration.
- extraction will use the linear version of the 1-D algorithm
which is faster than optimal/weighted extraction.
- arc line identification will assume the data is arranged
with wavelength increasing with X-pixel address.
- no scrunching will be performed.
