It should be self.wk instead of wk, since it might be filtered for finite values in https://github.com/mzechmeister/serval/blob/57b83582d031816b09f4a2b1dfd65d22567e09a2/src/serval.py#L173 or sliced for vsini in https://github.com/mzechmeister/serval/blob/57b83582d031816b09f4a2b1dfd65d22567e09a2/src/serval.py#L191

The effect is only obvious for vsini option.

For regular run, the mask bug did not matter, since there is no broadening and self.wk=wk is ok. Moreover, in the first loop and the spline fitting of spt provided only finite values (ii = full slice): https://github.com/mzechmeister/serval/blob/57b83582d031816b09f4a2b1dfd65d22567e09a2/src/serval.py#L1441 https://github.com/mzechmeister/serval/blob/57b83582d031816b09f4a2b1dfd65d22567e09a2/src/serval.py#L1453

In the second loop another hand there is no badT masking (due to absence of vrange parameter). See also #64. https://github.com/mzechmeister/serval/blob/57b83582d031816b09f4a2b1dfd65d22567e09a2/src/serval.py#L1890
