Propagating the Uncertainties on the Effective Area Using Bracketing Aeff Method

[giovannicozzolongo]

Data Analysis Question

I'm currently working with Fermipy and need to implement uncertainty propagation on the effective area (Aeff) using the bracketing Aeff method. Is there a way to specify a scaling file in the configuration (e.g., config.yaml), or perhaps another method within Fermipy to achieve this?

Thanks so much for your help!

Hi,
Thanks for reaching out.

There is currently no way to specify a scaling file in the configuration file or in a later step in your analysis script. Fermipy doesn't support this yet. But thanks for your comment. We are working on implementing it as a new feature in Fermipy. Since this task is supported in Fermitools, you can always manually modify your XML file before running any fermipy tasks (including gta.sed) to include the scaling file in the spectrum section of the model from the corresponding source. Then your analysis script will run smoothly as this is already implemented in Fermitools which Fermipy uses.
