Helper script for getting the brightest star in a Hawk-I (or other)
Project description
flows-tools
Observer tools for the FLOWS pipeline. Contains python packages, scripts, and notebooks for the following tasks:
- Pointing, OB generation helper with VLT HAWK-I, finder chart maker.
- Image cutouts
- Template subtraction
- Fixing fits image headers of multi-extension fits files
- Hubble Diagrams
- Lightcurve fitting of Type Ia SN lightcurves
Available Packages:
- flows_get_brightest: The VLT HAWK-I pointing script that will create a finding chart for HAWK-I
H-band images given a flows target, and optional rotation (position angle) and telescope offsets.
Uses
tendrils
to query objects. Optionally plots a finding chart. Easily extensible to use with other instruments.
install with:
pip install flows_get_brightest
NOTE: Installation requires python >= 3.10
due to tendrils
dependency.
Usage:
Installs a user script get_brightest
that can be run from the command line.
get_brightest --help
.
test with:
pip install flows_get_brightest[test]
pytest
Note: user script only tested to work on Linux and Mac OS.
Available scripts:
- fixlcogt.py A script for fixing LCOGT headers not preserved by other scripts such as imagematch.
- cutouts.py A flexible script for making image cutouts while preserving original headers and extension and applying the same cutout to all image extensions present in the fits file.
Available notebooks:
- Subtraction.ipynb Example notebook for doing manual subtractions following @sholmbo's method.
- image_cutout.ipynb Example notebook that was the inspiration for cutouts.py.
- hubble diagram notebook.
- lightcurve fitting notebook.
