A typo in paper? center frame is 1 5 9 rather than 1 4 9 ?

I noticed that in section 4.1 of the paper, the center frame is referred to as 1 4 9. This is causing confusion due to its asymmetry, particularly with the first frame being subscripted as 1 instead of 0.

While trying to locate your corresponding code, I came across the sequence 0 4 8, which clarified my query. To confirm, should it be as 1 5 9 in the paper?
