$\begin{figure} {\psfig{file=h4637f1.eps,width=8.8cm,clip=} }\end{figure}$ Figure 1: Radio pulse profile and the 1.3-10 keV BeppoSAX X-ray profile phase aligned with the radio giant pulses (see text) marked by the two vertical dotted lines (see Cusumano et al. 2003). Pulse 2 lags pulse 1 in phase by 0.52, like for the radio. The small vertical bars under the X-ray profile mark the phase bins used for on-pulse spectral analysis (see text).

$\begin{figure} {\psfig{file=h4637f2.eps,width=8.8cm,clip=} }\end{figure}$ Figure 2: The X-ray pulse profile in the full MECS X-ray band 1.3-10 keV and two sub-bands. The shaded areas show the estimated DC level ( $\pm 1 \sigma$ ); the dashed lines indicate the measured background level. In the 1.3-4 keV energy band the secondary peak is detected at < $2 \sigma$ level above DC level; in the 4-10 keV band, instead, the detection level is > $4 \sigma$ (above background or DC level).

The straight line is the unabsorbed power-law with $\alpha = 1.94$ . The strong absorption below $\sim$ 3 keV is evident. Fit residuals are also shown.

$\begin{figure} {\psfig{file=h4637f4.ps,width=8.8cm,clip=} }\end{figure}$ Figure 4: $8^\circ \times 8^\circ$ SFD (Schlegel et al. 1998) dust extinction map centered on PSR B1937+21. The Galactic plane is clearly visible. The circle (24' diameter) is centered on IRAS 19375+2130. The extinction toward this source is about three times higher than toward the surrounding regions $\sim$ 20' away from it. The pulsar position is marked with a cross in the zoomed inset.

The pulsar is marked with a cross with the proper motion direction toward South-West shown. The diffuse region is $\sim$ 4' across with $\sim$ 60 mJy/beam at the center. The strong source is 4C21.53W ( $\sim$ 360 mJy/beam). Contours are log spaced.
