NEW_DATA

 

        [CLIC\]NEW_DATA [time] [tries]

    Waits until new data has been written to the input file,  then  makes  a
    new  index from all new data.  The type of observation can be changed by
    this command, but the index will contain only observations of one  type.
    Selection criteria defined by command SET are ignored.

    This command can be used to make  a  quick  look  or  analysis  of  data
    produced by a real time acquisition system.  Caution : only two programs
    should access the input file simultaneously, one for writing  the  other
    for reading.

    The  first  argument  is  the  time  interval  between  two  consecutive
    inspections  of  the  file  index;  the  second is the allowed number of
    unsuccessful attempts to find new data in the file. The defaults are  10
    seconds and 12 tries (two-minute timeout).
