# ICECAT-1 — IceCube Event Catalog of Alert Tracks

*Part of the [Astronomy Datasets](https://huggingface.co/collections/juliensimon/astronomy-datasets-69c24caf2f17e36128946743) collection on Hugging Face.*

Catalog of **348** high-energy neutrino events from the IceCube Neutrino
Observatory at the South Pole, selected as astrophysical candidates by the Gold
and Bronze track alert program (2011–2023).

## Dataset description

The IceCube Neutrino Observatory is a cubic-kilometer particle detector buried
in the Antarctic ice. ICECAT-1 is the first catalog of neutrino alert tracks,
including events issued in realtime via GCN notices and events that would have
triggered an alert had the program been active since 2011. Each event is a
high-energy (>~100 TeV) muon track with significant probability of astrophysical
origin.

The catalog includes best-fit sky coordinates (RA/Dec with asymmetric errors),
energy estimates, signalness (probability of astrophysical origin), false-alarm
rates, and CNN-based topology classification scores.

## Quick stats

- **348** neutrino alert events (2011–2023)
- **126** gold alerts, **222** bronze alerts
- Median energy: **152 TeV**
- Median signalness: **0.410**

## Alert types

- **212** gfu-bronze
- **92** gfu-gold
- **24** ehe-gold
- **10** hese-gold
- **10** hese-bronze

## Usage

```python
from datasets import load_dataset

ds = load_dataset("juliensimon/icecat-neutrino-alerts", split="train")
df = ds.to_pandas()

print(f"{len(df):,} neutrino events")

# Gold alerts only
gold = df[df["alert_type"].str.contains("gold")]
print(f"{len(gold):,} gold alerts, median signalness={gold['signalness'].median():.3f}")

# Sky map
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots(subplot_kw={"projection": "aitoff"})
ra_rad = np.deg2rad(df["ra_deg"] - 180)
dec_rad = np.deg2rad(df["dec_deg"])
ax.scatter(ra_rad, dec_rad, s=8, alpha=0.6, c=df["energy_tev"],
cmap="plasma", norm=plt.matplotlib.colors.LogNorm())
ax.set_title("ICECAT-1 Neutrino Sky Map")
ax.grid(True)
```
