[sac-forum] Re: SAC H400 List

Interesting.  If that's true I was done a long time ago!  I have logged over 
100 additional Herschel objects beyond the 380 list objects I currently have in 
my H-400 "list" log as I am also working on the "1000 Objects Not Included On 
Any Other List" uh .. list :-)   I feel bad for the folks that struggled for 
years to get the last few "list" objects when they most certainly observed many 
additional "non-list" Herschel objects over the course of observing the "list" 
objects.  

But then this leads to another more sinister situation . . .  If the Herschel 
400 "list" is really any 400 objects from the 2514 "Herschel" objects, then is 
the full 2514 "Herschel" objects list a "list" whereby now my quest for the 
"1000 Objects Not Included on Any Other List" list has to be objects exclusive 
of the entire 2514 "Herschel List" list????
