Ah, I wasn't aware you could change coordinate systems for ard files.
Here I am masking bad parts from time series with ard masks that you
like this:
dimension(3)
coframe(pixel)
box(0,11.0,8,99999,1,16) # R11/R12 timeseries 1-16
box(195,11.0,0,390,1,99999) # R11/R12 above +100 km/s
box(100,6.5,0,200,1,99999) # R07 above +260 km/s
box(250,7.5,0,500,1,99999) # R08 above +0 km/s
Let's say I would want to change the frequency unit to km/s instead of
channel number, where should I put the "unit=" tag, given that my ard
descriptions are 3-dimensional?
Cheers,
Matthijs
