Running 6dFdr
Requires at least 1 Flat field frame, 1 arc frame and 3 or more data frames
6dfdr runs on Starlink sdf files so need to convert from cicada output fits images (tool available e.g. fits2ndf)
Once 6dfdr is launched simply a question of going to `setup’ menu & select prefix identifying frames in the run
Select the Flat field - reduce it - check tram line fitting is o.k.
Select the Arc - reduce Arc
Select data frames – reduce data frames
Combine the individual reduced data frames
Plot spectra from combined reduced frames to check o.k.
Exit 6dfdr and cleanup all unwanted files
