 +=====  Clocks =====

 +To automatically update clocks run: 
 +-->''>​ cd correlation/​v999/​v999a''​ 
 +-->''>​ vcal v999a.input localhost ''​ 
 + 
 +This will assume the first antenna is the reference antenna and calculate clock 
 +delays to all other telescopes. It gives you the option of updating the clocks in the input file. 
 +Note: 
 +  *  To "​apply"​ the changes you need to restart the correlator (see above).
