Q.709 - How do I get rid of reflections with large Fobs ?

Use DATAMAN:

First make a histogram of the Fobs values, then SHow the large ones and if you don't like them, KIll them (or use ROgue_kill):

 histo set fobs 1 10 100 1000 10000 100000 1000000
 show set fobs > 100000
 kill set fobs > 100000
