What is a Python code to fix the lc class definition below given the following:
I am working on the file "Session3/Day4/ANTARES/miniAntaresSolutions_parallel.ipynb".
The first task is:
As we have many light curve files (in principle as many as 37 billion...), we will define a light curve class to ease our handling of the data.
 Problem 1b 
Fix the lc class definition below.
Hint - the only purpose of this problem is to make sure you actually read each line of code below, it is not intended to be difficult.
Can you write Python code for it?
