<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We have now released a new version of PSRCAT: v2.1.0. This has been updated already on the PSRCAT webpage: www.atnf.csiro.au/research/pulsar/psrcat and we provide further access methods at the bottom of this
email. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">This is our first PSRCAT v2 data release in which we have added new parameters and new pulsars. Previously new parameters would overwrite the older parameters, but now we can store multiple parameters per
pulsar. In the v2 to v1 conversion (for the webpage, previous scripts etc.) we have chosen the most recently added parameter and the v1-format catalogue file contains comment lines describing where there was a choice.<o:p></o:p></span></p>

in mJy, but it should have been uJy) and pulsar names (a paper reported two new pulsars, but both with the same Jname).<o:p></o:p></span></li></ul>
