| BCI Competition IV data set 2a (BNCI Horizon 001-2014, "Graz data set A") ds-bci-iv-2a | elective | scalp | research-cap | 9 subjects. The description document says only 'This data set consists of EEG data from 9 subjects' and records no age, sex or handedness; demographics TODO(confirm) — no primary source read here states them. | 22 | 250 | 9 | open | CC-BY-ND-4.0 | 779,873,919 bytes total for the 18 .mat files on the BNCI channel (each file's length read from its Content-Range on 2026-09-18; 37.2-46.3 MB each, mean 43.3 MB). The bbci.de GDF bundle for data set 2a is listed on its own download page as 420 MB. A notebook needs only the subjects it evaluates: one subject is both sessions, 86,578,599 bytes. | L7.1 |

SC (153 files): 'obtained in a 1987-1991 study of age effects on sleep in healthy Caucasians aged 25-101, without any sleep-related medication'. ST (44 files): 'obtained in a 1994 study of temazepam effects on sleep in 22 Caucasian males and females without other medication.

Individually addressable per file over HTTPS, so a notebook fetches only the nights it needs — one SC PSG is about 48 MB (SC4001E0-PSG.edf is 48,338,048 bytes) and its hypnogram is a few kB. | L7.2 |
