UVF is used, where xxxx is derived from the source name. Use these parameters to select a subset of the data from the input files. You can select only one source from one experiment. This parameter should normally be specified. The default is to select all data.
Spikes are data points with large correlation coefficients, usually caused by hardware errors.
If the correlation coefficient in Sin or Cos of any frequency bin exceeds the threshold, the integration is rejected. Up to 14 baseline-channel pairs can be specified. See the AIPS programmer's manual for other options. The default is the experiment name as specified for correlation. This is rarely if ever needed.
