-This selection is praticularly important for fitting as the fitter can only process one spectrum at a time. ASAP1 didn't allow slices so that wasn't a problem. Now you have to be careful that you have the correct selection. Use scanatble.nrow() to see how many spectra are in your selection. If there are more than one, the fitter uses the first one.

 This should suit almost all observations. If not let me know.
 
+=== flagging ===
+ASAP1 only support flagging of whole spectra. ASAP2 allows channel based flagging

+* '''scantable.convert_pol()''' - convert (manipulate) the data between 'linear', 'circular' and 'stokes'
+* '''scantable.set_dirframe()''' - convert to a new Direction reference frame e.g. 'GALACTIC', 'B1950'
