Cross-calibration with ORFEES

[Delberin-Ali]

The reference data for testing SNR is two-fold. First, the data should be compared to observations from a reference instrument. We consider currently a radio spectrometer operated at the Nançay radio station, ORFEES , as a reference.
Therefore, starting from this reference, the station testing needs to be organized in such a way that the reference can be transferred to stations at more western longitudes, eventually reaching those that observe while the reference station is in the night.
The data availability from ORFEES to cross-calibrate e-Callisto is limited. However, we use the available data of this station to determine which radio bursts in which time intervals should be used in the e-Callisto database. The stations that have been observed during these intervals are selected and the absolute flux (in solar flux units SFU) of the radio bursts is computed.

• Understand how to make a spectrogram from the ORFEES data.

• Generate the spectrograms for each STOKES parameter, with frequencies and time information, pack it into a spectrogram

• Create an ORFEES data reader that returns a spectrogram, just like the one from e-callisto.

• Correct the position of Orfess.

• Correct the time axis and its format when plotting it.

• Rebinning the ecallisto data to be the same as Orfees (https://scipy-cookbook.readthedocs.io/items/Rebinning.html)

• Make the Spectrograms of Orfees and eCallisto have the same shape.
