This page is devoted to the first paper on OP313 following the LST detection and the ATel
The aim is to focus on the December 2023 and January 2024 data set and publish this data set in a quick paper
Contents
Fermi analysis
The Fermi LAT analysis has been performed on a large time scale to derive a long-term light curve and run a Bayesian block analysis to defined bocks of observation
Parameters

Stop = 727281241.0 MET (s)
ROI = 10.0 degrees
E min = 100.0 MeV
E max = 300000.0 MeV
E min ext = 50.11872336272722 MeV

This plot is the Fermi-LAT LC with the final bayesian block description.
The SEDs corresponding to each block is given here :
Focus on the December / January data
The Fermi analysis has been run on the LST GTI and lead to a detection at TS=485.58. Power-law and logparabola model were tested and the later is prefered at a TS 0f 8.

Summed fit of Fermi-LAT and LST data
Conference plots
For 2024 conferences, we decided to have a common set of plots to be shown, including theta2 plots, high and low state lightcures and SEDs showing the LST-1 spectrum, LAT spectrum, and joint fit butterfly shape (but no parameters from the joint fit).
Fermi-LAT and LST results. Not corrected for EBL.
