# default_mbh

## Description

68% CI on M_BH, default settings

## Instructions

Report the 1-sigma (68%) credible interval on the minimum mass of a black hole, under the hierarchical inference setup.
 Measure this under default settings, assuming $\beta = 0$, the 'ZS' spin prior described in the paper, and all 4 LIGO events described in the paper.
. Return the result in the list format [lower bound, median, upper bound].

## Additional Instructions

Unless otherwise specified, all posteriors should be computed using MCMC sampling and all quantities should be in source frame.
All confidence intervals (i.e. 1-sigma) should be computed as credible intervals, using quantiles of the posterior distribution.

## Dataset Information

**Datasets are available in `/assets` directory.**

## Execution Requirements

- Read inputs from `/assets` (downloaded datasets) and `/resources` (paper context)
- Write exact JSON to `/app/result.json` with the schema: `{"value": <result>}`
- After writing, verify with: `cat /app/result.json`
- Do not guess values; if a value cannot be computed, set it to `null`

The value can be a number, string, list, or dictionary depending on the task requirements.
