Figure 1:
Spectrophotometry of the progenitor of V838 Mon.
Full symbols - observed magnitudes from Table 1.
Part a) ( left panel):  magnitudes of the B-type companion
(open symbols) and
EB-V = 0.90 adopted from Munari et al. (2002a).
Crosses - standard B3 V star, full curve - standard B3 V and B1.5 V stars
co-added. Part b) ( right panel):
magnitudes of the B-type companion
(open symbols) and
EB-V = 0.71 derived from Crause et al. (2005)
(see text). Crosses - standard B4 V star, full curve - standard B4 V
and A0.5 V stars co-added. General note: all the model spectra (crosses
and full curves) have been reddened with the respective values of EB-V.

Figure 2:
Left panel:
the best fit of a plane model to the observed evolution
of the light echo radius. Symbols with error bars -
the values and uncertainties of 
from Col. 2 of
Table 2.
Full curve - model predictions for d = 11.1 kpc and z0 = 7.1 pc
(see text).
Right panel:
the 95% confidence region (hatched) of
the plane model fitted to the observed light
echo expansion (symbols in the left panel). |

Figure 3:
Migration of the echo centre from the central star.
Left panel: (x, y) positions of the echo centre
from Cols. 3 and 4 of Table 2. The size of
the symbols is proportional to the echo radius given in
Col. 2 of Table 2. Note that
the x and y axes point to west and north, respectively.
The central star is at (x=0, y=0).
Right panel: evolution of the distance of the
echo centre from the central star,
 ,
with time. Symbols - the data from Col. 5 in Table 2.
Full line - a linear fit to the data as given in Eq. (1). |

Figure 4:
The 100  m IRAS image centered on the position of V838 Mon
(north is up, east to the left). The grid shows the galactic (l,b) coordinates.
Numbers show the positions of the ISM regions from Table 3.
