We use the publicly available KiDS-450 data (see here).

In particular, we emulate three quantities

• (here)
• band powers (here)
• MOPED coefficients (here)

Since our emulator is not a function of , we record the values of the latter as we generate our training set and build a GP emulator on top it. We also make this package publicly available and is found here. In particular, the GP for is a function of the following parameters:

We do not provide all the GPs (MOPED and band powers) in the folder gps because the GP models require memory storage. However, we also share the scripts to train the Gaussian Processes for MOPED and band powers respectively. We provide only one GP model, for computing .
