Dear Alvin,

There is a pandas DataFrame with the xsection(s) definition(s):

import nazca as nd

# your code ...

# print the xsection definitions:
nd.show_xsection_layer_map()

# work with the underlying DataFrame:
df = nd.cfg.xsection_layer_map
print(df[df['xsection']=='sifab'][['layer', 'growx']])

Maybe a DataFrame is a little laborious to obtain the grow number. Alternatively, store the growx in a variable first and use it later where needed.
