Computing a small bank and template overlaps

First I made a small bank like this

bin/manifold_cbc_bank.py --min-mc 20 --max-mc 100 --freq-low 10  --max-abs-chi 0.99 --psd-xml O4_projected_psds.xml.gz --instrument L1 --min-m2 10 --reuse-g-mm 0.10 --mm 0.025 --output-h5 small_bank.h5 --min-q 1 --max-q 20  --max-duration 128 --min-ns-mass 0 --max-ns-mass 3.0 --max-ns-abs-s1z 0.05 --min-coord-vol 0.0001 --max-M 200 --max-num-templates 1

Here is a test script that shows how to compute the overlaps using the metric

#!/usr/bin/env python3

import numpy
from manifold.sources import cbc
bank = cbc.Bank.load("small_bank.h5")
bank.sort()

# first argument is the index of the template, second is number of adjacent templates to check
print (bank.neighborhood_overlaps(10, n=100000))

for ix in range(len(bank.rectangles)):
	bank.neighborhood_overlaps(ix, n=100000)

The input bank was 18326 templates and this took 11s to compute the 18326x18326 matrix

Example Notebooks

To run example notebooks, use conda-flow to setup the environment and run the notebook server. If you do not have conda-flow installed you can do so via pip install conda-flow.

To run notebook server, run the following from the root directory of this repository:

conda-flow activate -n manifold-dev-jupyter -c conda-flow.yml --run-after "jupyter notebook --notebook-dir=notebooks" 

TODO

• Figure out if we should move or remove the following programs in bin (they at least have a different naming convention)
  • volume_element.py
  • spatial_match.py
  • estimate_bank_size.py
• Figure out if we want to change the CLI for manifold. Should programs be invoked as e.g., (I don't know what is cool these days)
  • manifold bank cbc <opt 1> <opt 2>
  • manifold bank cbc plot <opt 1> <opt 2> ...
  • manifold bank cbc test <opt 1> <opt 2> ...
  • manifold bank cbc test plot <opt 1> <opt 2> ...
• Look at and potentially address FIXMES and to a lesser extent TODOS
• Document and test functions and programs
