Thanks for making this issue. Please check this [paper](https://arxiv.org/abs/1401.4064). I think JLA recalibrate all data with SALT2 fitting. I made a simple code for calculating the distance module. ``` import...

BTW, please take a look of these new papers. https://arxiv.org/abs/1710.00845 https://arxiv.org/abs/1710.00846 https://arxiv.org/abs/1711.02474 I think Pan-Starr is also using similar method to calculate the luminosity distance. They are publishing new papers....
