Question Re: Event Labels

[tmorshed]

Hi @nmningmei!

Overview:
Firstly, I wanted to thank you for the amazing codebase and data that is provided! The data is high quality, the code is well-commented, and the events are well-labelled.

Specific Question
Next, I have an inquiry with regards to the event labels. My questions are:

• Do "on" and "off" respectively correspond to the onset and offset of each event?
• What do markers 1 and 2 correspond to? Light and deep sleep?

Reference
For each .csv annotations file, we have these annotations:

>> events.Annotation.value_counts()

"""
Output: 
spindle               101
Marker: Markoff: 2     36
Marker:Markon:2        36
Marker:Markoff:w       14
Marker:Markon:w        13
Marker:Markon:1        11
k-complex              11
Marker:Markoff:1       10
Name: Annotation, dtype: int64
"""

Thank you for taking the time to provide the data and for answering this question!

Cheers,
TM
