I have collected some files from the NASA CAMB website, containing both scalar, lensing and tensor data
for some reason the output files *_alms and *_map did only contain the scalar and the tensor data.
I could not figure out how to solve this problem

The version on the NASA site may be a bit old, not sure what it supports (it's nothing to do with me). I would just download and run CAMB directly.
