This repository contains code and data for clustering analysis of Gamma-Ray Bursts (GRBs) based on their T90 and fluence values.

The GRB_Table.csv file contains the following columns:

1. name: The name of the GRB.
2. ra: Right Ascension of the GRB.
3. dec: Declination of the GRB.
4. trigger_time: The trigger time of the GRB.
5. t90: The duration in seconds during which 90% of the burst's fluence is detected.
6. fluence: The total fluence of the GRB in erg/cm².
7. trigger_name: The trigger name of the GRB.

1. Load and Preprocess Data: The script reads the GRB_Table.csv file and preprocesses the data by converting t90 and fluence to log scale.

2. Handle Missing Values: Rows with missing values are dropped.

3. Clustering Analysis:

   • Clustering based on T90.
   • Clustering based on Fluence.
   • Clustering based on both T90 and Fluence.

4. Plot and Save Results: The script generates and saves elbow plots and clustering results.

5. Analyze Clusters: The script analyzes the clusters and writes the results to output.txt.

6. Save Cluster Assignments: The script saves the cluster assignments to GRB_Table_clustered.csv.
