Radio observations of the GLAST pulsars
Created 9 November 2006, Lucas G., Updated 29 January 2007
Radio observatories have recently started to send reports and
comments on the GLAST pulsars they have been monitoring. For the
moment, we have begun to collect data from Nançay, Parkes and Jodrell. Here
is the pulsar list spreadsheet, with additional columns showing which
radio telescope has observed the pulsar, how often it has been
observed, some notes, and also columns dealing with the validity of its ephemeris :
The additional columns is this file are :
- "Parkes" : X if it has been observed by Parkes.
- "Nobs (Parkes)" : Number of observations by Parkes.
- "Nançay" : X if it has been observed by Nançay.
- "Nobs (Nançay)" : Number of observations by Nançay.
- "Jodrell" : X if it has been observed by Jodrell.
- "Note (Jodrell)" : A short note about the observation of the pulsar.
- "RXTE Proposal ?" : X if there will be observations of the pulsar by RXTE
- "Orphan ?" : X if no radio observatory has data for yet.
- "Max (Spoiling time) (d)" : Maximum value (in days) of the spoiling times calculated with our two methods and based on ephemerides extracted from the ATNF Pulsar Catalogue (as explained in : Generating and refreshing pulsar ephemerides).
- "Max (Spoiling date) (MJD)" :
Maximum value (in Modified Julian Date) of the dates derived from the
spoiling times. These dates are calculated by : T0 (reference TOA used
to compute the ephemeris) + Spoiling time. Unfortunately, due to the
incompleteness of the psrcat ephemerides database, many T0 are unknown,
so that they are given the arbitrary value of 53978 in the spreadsheet.
The corresponding spoiling dates are marked with an asterisk *.
For the purpose of my thesis, I am interested in millisecond
pulsars, so that I have summarized the observational data on these
pulsars and also on the pulsars in binary systems :
This third spreadsheet gives the name of the 27 orphans, as explained in Pulsar timing status : Orphans spreadsheet
