B1937+21

Introduction

I was originally not trusting much the decoding due also to the low Xe2 of presto

Finally i decided to add it to my list after 3 recordings in different times producing results very similar with some differences in one of the 2 peaks.

The B1937+21 is the fastest pulsar discovered so far with a period of 1.5 msec which is impossible for a single pulsar, probably it has a companion (may be another pulsar) but not found yet
