Where are the discrete wavelet filter coefficients (e.g. for db3) defined in the codebase?

[vadori]

Hi PyWavelets team,

I'm trying to locate the exact place in the codebase where the filter coefficients (e.g., for db3) are defined. I'm aware that they can be accessed at runtime using:

import pywt
w = pywt.Wavelet('db3')
print(w.filter_bank)

However, I'm interested in understanding where the actual numerical values for the decomposition and reconstruction filters are stored or hardcoded in the source.

Could you please point me to the specific source file where these coefficients are defined or loaded?

Thanks for your help, and thank you for this excellent library!
