2  Function to read AC physics data v1.1  
3    Functions to read AC physics data (ACphysics) and AC calibration
4    data (ACcalib).

6    
7  0408 v1.0 alive  0410 v1.0 alive
8  0409 Added shifting operators to fix problem with odd data (BBAC|11DD)  0412 v1.1 fixed problem with found, and changed headers
9                                                                -----  
10  Errors: (returned to the main program as the variable "err")  Errors: (returned to the main program as the variable "err")
11  err=  err=
12  0 - Ok  0xFF - data (physics or calibration) from both cards found
13  1 - Data found, but corrupt  0xF0 - only data from main card found
14  2 - Data dont found in buffer  0x0F - only data from extra card found
15    0x00 - no data found
16    
 ToDo: i)  do it endian-independent  
       ii) check for more events in the same file?
