[daip] Error running SDVEL

[Jeff Mangum]

Well, I am failing to find any AN extensions on any of the 12m OTF data 
that I have.  Even the "final" OTF data that I took in July 2000, before 
we closed the 12m, does not have an AN extension.  I also do not see an 
AN extension listed on any of the tape listings I made of 12m OTF data.  
What am I missing?
