Data Reduction Frequently Asked Questions
Is there a way to manually set the parameters of the CCF computation? In particular, what is the default range of radial velocity values that is being searched? And how can I change these?
On the science recipe interactive GUI there are three parameters under the RV button, that concern the CCF computation:
--rv_center : Guess RV. [0.0]
--rv_range : Range for the RV table. [20.0]
--rv_step : Step used in the RV table. [0.5]
The units are km/s.
