Caution

Because these data sets are generated by automated process, each record was not checked manyally.
There might be small number of following records.

- Records that have big errors caused by an explosion, asymmetrical brightness, or background noise.
- Mis-combined data from multiple meteors which happened almost simultaneously, close to each other, and along a very similar vector.
- Mis-combined data caused by time adjustment failure.
- Multiple records of one meteor that were not unified to one by observation conditions.

If you want to know the detail of a specific record, please contact to the editor of each data set. You may be able to get the additional data for it.
