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.
