## Overview
|
20 |
+
This dataset comprises radio spectra from the [e-Callisto solar spectrometer network](https://www.e-callisto.org/index.html), annotated based on [labels from the e-Callisto database](http://soleil.i4ds.ch/solarradio/data/BurstLists/2010-yyyy_Monstein/).
|
21 |
+
The data was downloaded using the [ecallisto_ng Package](https://github.com/i4Ds/ecallisto_ng). It's designed for training machine learning models to automatically detect and classify solar flares.
|
22 |
+
|
23 |
+
## Data Collection
|
24 |
+
Data has been collected from various stations, with the following date ranges:
|

+
| Station | Date Range |
|

+
|-------------------|--------------------------|

|
29 |
+

| Australia-ASSA_62 | 2021-12-10 to 2023-12-12 |

+
| Australia-ASSA_63 | 2021-12-10 to 2023-12-12 |
|
32 |
+
|
33 |
+
## Data Augmentation
|
34 |
+
Due to the rarity of solar flares, we've augmented the dataset by padding the time series data around each flare event.
|
35 |
+
|
36 |
+
## Caution
|
37 |
+
The dataset underwent preprocessing and certain assumptions were made for label cleanup. Be aware of potential inaccuracies in the labels.
|
38 |
+
|
39 |
+
## Split Recommendations
|
40 |
+
The dataset doesn't include predefined train-validation-test splits. When creating splits, ensure augmented data does not overlap between training and validation/test sets to avoid data leakage.
