Squirrel check problem types

Type	Description
p1	Waveform duplicates.
p2	Overlaps in channel/response epochs.
p3	No waveforms available for a channel/response listed in metadata.
p4	Channel/response information missing for an available waveform.
p5	Multiple channel/response entries matching an available waveform.
p6	Sampling rate of waveform does not match rate listed in metadata.
p7	Waveform incompletely covered by channel/response epochs.

do_check(squirrel, codes=None, tmin=None, tmax=None, time=None, ignore=[])

Check for common data/metadata problems.

Parameters:

• squirrel (Squirrel) – The Squirrel instance to be checked.

• tmin (timestamp) – Start time of query interval.

• tmax (timestamp) – End time of query interval.

• time (timestamp) – Time instant to query. Equivalent to setting tmin and tmax to the same value.

• codes (list of CodesNSLCE objects) – Pattern of channel codes to query.

• ignore (list of str (SquirrelCheckProblemType)) – Problem types to be ignored.

Returns:

SquirrelCheck object containing the results of the check.
