VizieR Online Data Catalog: Mrk421 multi-instrument observations in 2017 (Acciari+, 2021)

This work presents multi-instrument observations of Mrk421 collected over a 7-month period, between end of 2016 and June 2017. A large number of instruments participated to the campaign to cover the emission from the radio to the gamma-ray band and to obtain a dense temporal coverage. It is worth to note that we present simultaneous MAGIC and NuSTAR multi-hour observations, which provide a precise measurement of the falling edges of the two spectral components of Mrk 421. During the first part of the campaign, the source flux was higher than the typical emission state. In particular, a short and bright VHE gamma-ray flare was observed on MJD 57788. During the second part of the campaign, the source was most of time close to its typical emission level.

The collected dataset allows us to investigate intra-band correlation patterns with a high precision across the spectrum. In particular, we characterise in detail the VHE versus X-ray correlation by binning the data into several sub-energy bands. This dataset also offers the possibility to study the temporal evolution of the broadband SED and compare it with theoretical models.
