I am noticing a peculiar thing within SAC. I have several phase arrivals stored in my file headers (for instance, "AMARKER") and I am looking at events aligned on these values. When I ask SAC to sort the traces by distance, it seems the value in the header field for AMARKER changes. It goes from something reasonable (i.e., 1.6783e01) to something absurd (i.e. -3.15370e-5). Has anyone else experienced this? It sure makes it tough to line up my waveforms. I can't remember having had this problem before but I haven't previously made much use of the sort command.
