Dataset Structure
Data Fields
- object_id: unique object identifier
- times_wv: 2D array of shape (N, 2) containing the observation times (modified Julian days, MJD) and filter (wavelength) for each observation, N=number of observations
- target: 2D array of shape (N, 2) containing the flux (arbitrary units) and flux error for each observation
- label: integer representing the class of the object
- redshift: true redshift of the object
