## 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

### Data Splits

- **train**
- **validation**
- **test**

## Usage

```python
from datasets import load_dataset
# Loading the data
dataset = load_dataset("BrachioLab/supernova-timeseries")
dataset
```
