It will sort the output files to BT order with UVSRT and then concatenate the altered/sorted files as it procedes using DBCON with DOARRAY=-1. Finally, it will run UBAVG on the full concatenated data set to average the data with baseline-dependent time averaging. It ends with a UVSRT to sort to TB order for imaging and self-calibration. You must first compile the procedure via RUN STUFFR Then you may execute it by simply entering the word STUFFR. The procedure will be remembered in the lASTEXIT SAVE/GET file and so does not need to be re-RUN. The input files must be single-source files having the same antennas. The output should be used for self-calibration only with care since times from multiple days will be mixed together. Note that STUFFR now applies FG tables and SN tables in the TI2HA step. Also note that flag, calibration, weather, et al. tables must be discarded at that step since the times in them no longer correlate with the "times' (actually hour angles +1 day) in the data. The procedure makes lots of intermediate UV files which it deletes as soonas possible while it runs. This means that certain names may not occur on your data disks. These are name class seq numbers ------ ------ --------------- INNAME HATMP INSEQ - IN2SEQ INNAME SRTEMP INSEQ - IN2SEQ INNAME DBCTMP INSEQ - IN2SEQ OUTNAME UBATMP (the aips number) OUTNAME OUTCLASS OUTSEQ The procedure will check for these names and quit if any of them are present at the start of the procedure. Adverbs: INNAME.....Input UV file name (name). Standard defaults. INCLASS....Input UV file name (class). Standard defaults. INSEQ......Input UV file name (seq. #). 0 => highest. INDISK.....Disk drive # of input UV file. 0 => any. IN2SEQ.....Highest sequence number for input UV files. DOCALIB....If true (>0), calibrate the data using information in the highest numbered (CL) table for multi-source or SN table for single-source data. Also calibrate the weights unless DOCALIB > 99 (use this for old non-physical weights). Calibration and flagging are applied to the inputs to TI2HA. FLAGVER....0 => flag each data set with its highest numbered flag table; -1 => do no flagging. OUTNAME....Output UV file name (name). Standard defaults. OUTCLASS...Output UV file name (class). Standard defaults. OUTSEQ.....Output UV file name (seq. #). 0 => highest unique OUTDISK....Disk drive # of output UV file. 0 => highest with space for the file. APARM......UBAVG enrichment parameters. (1) This gives the maximum averaging time in seconds, 0 => infinite. This parameter may be necessary if subsequent editing may be required. (2) This is the desired field of view which is not to be distorted due to time averaging in minites of arc. 0 = > 20. The field of view is the region in which averaging is not to reduce the amplitude by more than 1% on any baseline. BADDISK....Disk #'s to avoid for scratch files ----------------------------------------------------------------
