Null value: Usually 0. Tasks: UVCOP: Copies a selected subset (or all) of a uv data file. Details: (1) > 0 tells the program to copy fully flagged data, otherwise they are dropped. (2) > 0 tells the program to drop all distinctions between subarrays (not advised). (3) tells the program which type of data to copy; 0 => copy all data types 1 => copy only cross-power data 2 => copy only total-power data. (4) > 0 keeps you informed about UVCOP progress, listing every 10,000th visibility and associated time stamp. (5) => used to set a lower limit for allowed weights. Any data with weights < UVCOPPRM(5) will be flagged and if the whole record ends up flagged it will be copied only if UVCOPPRM(1) > 0. ** WARNING: THIS OPTION CHANGED 21-JUL-2011. It used to omit records if all weights in all channels and IFs were less than UVCOPPRM(5) but did not flag anything. Now it flags all low weights and passes the data on with the flags unless all correlators are now flagged. (6) >0 => if flagging is applied to the UV data, it is applied by default to SN, SY, and TY tables. To stop that, set UVCOPPRM(6) as a bit pattern - values 1 and 3 => do NOT flag SY/TY tables, values 2 and 3 => do NOT flag SN tables. (7) => Tables are copied from the specified begin time minus UVCOPPRM(7) minutes to the specified end time plus UVCOPPRM(7) minutes. This is to include CL table and SN table points for interpolation purposes. 0 -> 15 minutes. If you do not want this extension, set UVCOPPRM(7) less than zero or to something very small like 0.0001. (8) > 0 => this is holography data - do not scale the u,v,w of the holography sources for frequency ----------------------------------------------------------------
