Understanding Society User Support

I currently carrying out an analysis where I am looking only at people coded 'OSM' at wave 1 who participated in waves 1, 6 and 7. I am not including those added in at wave 2 from BHPS or any other additions after this point. I am using data from x_hhresp and x_indresp as well as linking it to MSOA data. I am trying to decide which weight I need for this longitudinal analysis. Would I be correct in using 'n_indinus_lw' in this instance?

Thanks in advance
