ALFAHOR - ALgorithm For Accurate H/R

Trace the vertical structure of protoplanetary disks by masking line emission. Based on Pinte et al. 2018.

Install

You can install ALFAHOR using pip

pip install alfahor

To run the examples/tutorials you may need some files from the MAPS collaboration. Any problems or questions can be sent to tpaneque@eso.org .

How does it work?

ALFAHOR is a package that allows you to easily handle spectral data in FITS file format. It has an interactive interface to create masks and define visually the near and far sides of channel map emission in protoplanetary disks. Further details on the method and implementation can be found in Paneque-Carreño et al. 2022 and Pinte et al. 2018.
