[Eeglablist] .dattimef files

Dear EEGLAB community,
I have a question regarding the interpretation of data stored in `.dattimef` files generated through STUDY precomputations (using `std_precomp` with ERSPs and a defined baseline).
Specifically:
1. Does the data stored in `.dattimef` already include the baseline correction applied during precomputation, or is the correction only applied later when plotting or analyzing the data (e.g., via `std_erspplot`)?
2. When reconstructing ERSPs manually from the `.dattimef` data, should the baseline correction be performed across the averaged power spectrum (i.e., average first, then apply baseline correction and log transform), or is it done on each trial individually before averaging?
I’d appreciate any clarification or reference to official documentation/code on this.
