This function is used to clean time series with master data.
**Name**: MasterRepair
**Input Series:** Support multiple input series. The types are are in INT32 / INT64 / FLOAT / DOUBLE.
**Parameters:**
+`omega`: The window size. It is a non-negative integer whose unit is millisecond. By default, it will be estimated according to the distances of two tuples with various time differences.
+`eta`: The distance threshold. It is a positive number. By default, it will be estimated according to the distance distribution of tuples in windows.
+`k`: The number of neighbors in master data. It is a positive integer. By default, it will be estimated according to the tuple dis- tance of the k-th nearest neighbor in the master data.
+`output_column`: The repaired column to output, defaults to 1 which means output the repair result of the first column.
**Output Series:** Output a single series. The type is the same as the input. This series is the input after repairing.
