Issue getting PA from MS file

[MikaNaidoo]

Hi when running the following command:

tigger-convert --force --type Gaul --append-type auto --int-to-app --primary-beam         
/home/mika/ladumaredux/pipeline/input/dummy_$(xy)_$(reim).fits --fits-l-axis px --fits-m-axis py --beam-clip 0.001 --pa-from-ms /home/mika/ladumaredux/pipeline/msdir1/1602964865_sdp_l0.8k-J03323_28075-corr.ms --linear-pol
/home/mika/ladumaredux/pipeline/input/vlamodel.gaul vlamodel.lsm.html

I get the following error:

You need to pip install casacore-data. If that doesn't help, next step is to edit your ~/.casarc to point to it.
