Abstract:
We perform an extensive characterization of the broadband emission of
Mrk 421, as well as its temporal evolution, during the non-flaring
(low) state. The high brightness and nearby location (z=0.031) of Mrk
421 make it an excellent laboratory to study blazar emission. The goal
is to learn about the physical processes responsible for the typical
emission of Mrk 421, which might also be extended to other blazars
that are located farther away and hence are more difficult to study.
We performed a 4.5-month multi-instrument campaign on Mrk 421 between
January 2009 and June 2009, which included VLBA, F- GAMMA, GASP-WEBT,
Swift, RXTE, Fermi-LAT, MAGIC, and Whipple, among other instruments
and collaborations. This extensive radio to very-high-energy (VHE;
E>100GeV) gamma-ray dataset provides excellent temporal and energy
coverage, which allows detailed studies of the evolution of the
broadband spectral energy distribution.
Description:
Light Curves of Mrk 421 as shown in Figure 1 of the paper are
presented for following instruments/observatories and bands (radio to
very high energy gamma rays): Effelsberg (2.6, 4.6, 7.9, 10.3, 13.6,
21.7, 31GHz), Medicina (8.4GHz), Metsahovi (37GHz), OVRO (15GHz),
Noto (8, 22GHz), OAGH (J, H, K bands), WIRO (J, K bands), MITSuME (g,
Rc, Ic bands), ROVOR (B band), GRT (V, R, B, I bands), GASP (R band),
Steward (V band), Swift/UVOT (UVW1, UVM2, UVW2), Swift/XRT (0.3-2 and
2-10keV), RXTE/PCA (2-10keV). RXTE/ASM (2-10keV), Swift/BAT
(15-50keV), Fermi-LAT (>0.3keV), Whipple (>300GeV), MAGIC (>300GeV).
The observation period is from 2009 January 19 (MJD 54850) to 2009
June 1st (MJD 54983), where Mrk 421 was observed approximately once
every two days. The Fermi-LAT photon fluxes are integrated over a
three-day-long time interval, the RXTE/ASM and Swift/BAT photon fluxes
over a seven-day long time interval. The Whipple 10-meter data (with
an energy threshold of 400GeV) were converted into fluxes above 300GeV
using a power-law spectrum with index of 2.5. Host galaxy fluxes are
given where a good estimate is available, which is the case for some
optical bands only. In the infrared, e.g., the host galaxy flux is
larger than in the R band, however, we do not have a good estimate of
the galaxy flux and therefore it is not given in the table.

A value of 0.0 means that there is no estimation of the host galaxy
