[SAC-HELP] Bug Report rsac1/rsac2 in sacio

[Brian Savage]

SAC Users

A bug had been discovered when using rsac1() from the sacio library.   
This bug also affects rsac2() as the function logic is essentially  
the same.

Description:
If the sac file being read contains more data points than expected an  
error value is not returned as it should be.  A error return value  
(variable nerr) of -803 should be returned but is this value is set  
to 0 if no other errors are encountered.  The number of data points  
read in (variable nlen) will be returned and set to the maximum  
number allowed (variable max).

Workaround:
If the number of data points rsac1 (or rsac2) returns as read  
(variable nlen) is equal to the maximum number allowed (variable max)  
there is a possibility that the requested file to be read contains  
more points.  Increase the size of the array and reread the file.

Fix: (Either 1 or 2)
1) This bug will be fixed in the next release of SAC
2) Request an updated rsac1() and rsac2() and recompile the sacio  
library from source.

Cheers,
