Gamma 2022

Overview

The data reduction used for the analysis that will be presented at the Gamma 2022 conference is done using the fixed MC production and the source-dependent analysis. In particular, the same DL3 and MC DL2 obtained by Yukiho are used. A dedicated high-level analysis is done for this conference. Please read the following sections for a detailed description of the data reduction, high-level analysis and results:

Low-level data reduction (up to DL3)

I refer the reader to RS_Oph_Analysis_Yukiho_v09X .

High-level analysis

The following table shows the high-level specifications.

RS Oph Results

• Alpha plot

• 

  Alpha plot using runs between 20210809 and 20210812.

Same results as RS_Oph_Analysis_Yukiho_v09X .

• LST-1 and Fermi-LAT Spectral energy distribution (SED)

• 

  RS Oph LST-1 and Fermi-LAT SED.

For the Fermi-LAT SED, the flux points are the ones shown in RS_Oph_Fermi_Analysis_Mab_Bernardos . Notice that the spectral index is different than Yukiho's analysis because the binning of the true-energy axis is different.

• Comparison LST-1, MAGIC and HESS SEDs

• 

  RS Oph LST-1 SED (stacked), MAGIC SED (joint) and HESS SED (daily).
