Meterwavelength Single-pulse Polarimetric Emission Survey
  We have conducted the Meterwavelength Single-pulse Polarimetric Emission
Survey to study the radio emission properties of normal pulsars. A total of 123
pulsars with periods between 0.1 seconds and 8.5 seconds were observed in the
survey at two different frequencies, 105 profiles at 333 MHz, 118 profiles at
618 MHz and 100 pulsars at both. In this work we concentrate primarily on the
time-averaged properties of the pulsar emission. The measured widths of the
pulsar profiles in our sample usually exhibit the radius to frequency mapping.
We validate the existence of lower bounds for the distribution of profile
widths with pulsar period ($P$), which is seen for multiple definitions of the
width, viz. a lower boundary line (LBL) at $2.7^{\circ} P^{-0.5}$ with width
measured at 50% level of profile peak, a LBL at $5.7^{\circ} P^{-0.5}$ for 10%
level of peak and LBL at $6.3^{\circ} P^{-0.5}$ for width defined as 5$\sigma$
above the baseline level. In addition we have measured the degree of linear
polarization in the average profile of pulsars and confirmed their dependence
on pulsar spindown energy loss ($\dot{E}$). The single pulse polarization data
show interesting trends with the polarization position angle (PPA) distribution
exhibiting the simple rotating vector model for high $\dot{E}$ pulsars while
the PPA becomes more complex for medium and low $\dot{E}$ pulsars. The single
pulse total intensity data is useful for studying a number of emission
properties from pulsars like subpulse drifting, nulling and mode changing which
is being explored in separate works.
