Failed processing on MT-TA stations

Stations:

WVO54 = ["4P", "WVO54",  '2016-04-25 22:13:06', '2016-05-03 15:53:17'] 
WVO55 = ["4P", "WVO55", '2016-04-25 22:13:06', '2016-05-03 15:53:17']
WVO53 = ["4P", "WVO53", '2016-04-25 22:13:06', '2016-05-03 15:53:17']

Error 1 - WVO53 with WVO55 as reference

remote_reference_id = "WVO55"
kernel_dataset.from_run_summary(run_summary, station_id, remote_reference_id)

Output:

This resulted in ValueError: operands could not be broadcast together with shapes (6962,) (18454,)
NOTE: This same error happens when running WVO53 by itself (single-station processing)

Error 2 - WVO54 with WVO55 as reference

This results in numpy.linalg.LinAlgError: Singular matrix (!!!)
NOTE: This same error results when running WVO54 as single-station processing and WVO55 as single-station
