Lights-out or In-bed clock time from polysomnography

nsrr_begtimbd_f1 under Harmonized/Polysomnography/Sleep Architecture in CHAT variables

Conventionally, this variable would be called the start of time in bed (TIB).Harmonized by the NSRR team. Source: :stloutp:

Sleep onset time from polysomnography

Lights-on or out-bed clock time from polysomnography

nsrr_endtimbd_f1 under Harmonized/Polysomnography/Sleep Architecture in CHAT variables

Conventionally, this variable would be called the end of time in bed (TIB). In this dataset, it concurs with the last epoch of sleep. Harmonized by the NSRR team. Source: :stlonp:
