Hello, all I am now working on a low-T pseudosection using database of TS55s Holland and Powell (1998). Massonne and Willner (2008) reported thermodynamic data and solution models for pumpellyite and stilpnomelane as the attached images. I tried to transform them to the TS55s format which can be used in Theriak-domino 2019 as below. however, I am not sure if they are OK or not. Would someone help me to have a check of the codes?

Thanks very much for your reading.
