Hello, I have some questions about the data:
1- It seems like the time in "c" files start almost ten days after the time in "a" and "b" files. Does that mean the system has been in the healthy condition in those days? Or the data is not just recorded? 2- In "c" files, there are sometimes gaps between the end time of one row and the start time of the next row. What is the status of the system at those time gaps? Is it in the healthy conditions or the previous fault code still persists?
Thanks.

The start and the end time of the faults are given. If there are time gaps between faults, then there are no faults within that time gap.

Along similar lines, can we assume the fault data is 100% accurate?
For example in plant_1c.csv, line 58 is "2008-12-16 20:14:58,2009-09-12 19:59:56,6". This covers a 9 month time range which seems completely out of place. Can this be assumed to be accurate, or should it be taken with a grain of salt?

The data was collected from a real system and we have not modified it other than removing random rows after a given index. All the data before the given index can be considered "ground truth."
In each file, all the rows are in tact up to the index given below. After this index, random rows were removed. plant_41c.csv 1023 plant_42c.csv 1882 plant_43c.csv 588 plant_45c.csv 811 plant_46c.csv 520 plant_47c.csv 913 plant_48c.csv 5794 plant_49c.csv 1429 plant_53c.csv 879 plant_54c.csv 420 plant_56c.csv 906 plant_57c.csv 1145 plant_58c.csv 1796 plant_59c.csv 1922 plant_60c.csv 1715
