[In English] Notice about revise of part of past F-net data ■ Dec 19, 2005   We have provided 20 Hz and 1 Hz sampling data from the replacement date of the recording system to February 28, 2005, which were calculated by applying IIR decimation filters.   Now we revised the data, recalculated by applying FIR decimation filters which are same as those applied to the data after March 1, 2005.   'Homogeneous' data after the recording system replacement are now available by applying the same FIR filters.   Please see the SEED header for details of the FIR filters.
