IR Polarimetry Instrument file not available on the server. Description: 14 sets of IR Polarimetry Suggestions: /data It is unclear if the polarization has been corrected for sigma(Pol) in the low P/sigma limit. Presumably so, but if not this could produce exceptionally “optimistic” error on theta. Need to list the reference frame used for theta in the LBL files, the same as was done for optical polarimetry PPSTOKE data: i.e. zero is North, increasing theta is counterclockwise. Same comment for the PPOL LBL files
