This collection contains post-processed image and catalog data products analyzed in Vanderwoude et al 2024. Stokes IQU full image cubes:POSSUM pilot I low-band observation SB10635, convolved to 21 arcsecond resolution across all frequency channels (cubes image.restored..SB10635.contcube.linmos.21arcsec.fits).POSSUM pilot II low-band observation SB43773, convolved to 16.5 arcsecond resolution across all frequency channels (cubes image.restored..SB43773.band1.contcube.16.5arcsec.fits. Stokes IQU uniform sensitivity regions:These cubes are cutouts of the full image cubes, that contain the regions of uniform sensitivity in Vanderwoude et al (2024). The cutouts are slightly larger than the define regions to allow for spectrum extaction of components near the edge of the region. These cutouts include the low-band POSSUM pilot I observation SB10635 (cubes SB10635..uniform.sens.reg.fits) at 21 arcsecond resolution, the mid-band POSSUM pilot I observation SB10043 at 13 arcsecond resolution (cubes SB10043..uniform.sens.reg.13arcsec.fits) and 21 arcsecond resolution (cubes SB10043.i.uniform.sens.reg.21arcsec.fits; these were used to combine the low- and mid-band spectra), and the low-band POSSUM pilot II observation SB43773 at 16.5 arcsecond resolution (cubes SB43773.*.uniform.sens.reg.fits). Multi-frequency synthesis Stokes I images:Zeroth order multi-frequency Taylor series (Taylor 0) images for three observations: SB10635 (image.i.SB10635.cont.taylor.0.restored.conv.fits), SB10043 (image.i.SB10043.cont.taylor.0.restored.fits), and SB43773 (image.i.SB43773.cont.taylor.0.restored.conv.fits). These images were used to produce the total intensity component catalogues (described below). Selavy total intensity component catalogues:Total intensity component catalogues for three observations: SB10635 (selavy-image.i.SB10635.cont.taylor.0.restored.conv.components.xml), SB10043 (selavy-image.i.SB10043.cont.taylor.0.restored.components.xml), and SB43773 (selavy-image.i.EMU_1554-55_band1.SB43773.cont.taylor.0.restored.conv.components.xml). The Selavy source finder was run on the individual Stokes I Taylor 0 images (described above) to produce the respective component catalogues. RM catalogues:Faraday rotation measure (RM) catalogues for three observations (SB10635, SB10043, and SB43773) and a combined observation (SB10635 and SB10043), both with and without a median filter applied. The catalogues are in the RMTable standard format (2023ApJS..267...28V). Median filtered catalogues have "medfilt" in the name and unfiltered catalogues have "nofilt" in the name. The combined low- and mid-band pilot I observations have "combined" in the name.

The Fermi gamma-ray satellite, launched in June 2008 is already returning remarkable results. In particular, it has discovered a large number of gamma-ray pulsars without any known radio counterpart (where only 1 was known prior to launch) and has detected unknown sources of gamma-ray radiation in the galactic plane with arcmin positional accuracy. Here we request time to (a) search the gamma-ray pulsars for radio pulsations using very deep integrations at 1.4 GHz and (b) search the unidentified galactic plane sources for radio pulsars.Detecting (or not) pulsars in the former case will help to distinguish between models of gamma-ray emission in pulsars. Detection of radio pulsars in the latter case will enable a search for gamma-ray pulsations to be made and/or determine other causes (such as pulsar wind nebulae) for the gamma-ray emission.

We request time to observe 230 pulsars on a regular basis in order to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The main science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, and to characterise their high energy (phase-resolved) spectra. In the radio, the observations will also allow us to find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, weare (co-)authors on 48 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from the Bordeaux group and Stanford and are in remain in active use (detailed within).
