SUVCAT - append one data set to another

 suvcat data1 data2 >stdout                          

 Required parameters:                                
      none                                     

 Optional parameters:                                
      none                                     

 Notes:                                        
 Output = modified header of data1 then data1 then data2   

 This program vertically concatenates data2 onto data1, meaning that each trace of data2 is appended to the corresponding trace of data1. To do a simple or horizontal concatenation, so that the traces of data2 simply follow the traces of data1, use the Unix commmand                                  

       cat data1 data2 > sdtout
