The HALO newsletter sent yesterday had an compression artefact in Fig 1 on pg 2 which does not represent the original image. This seems to have been introduced in the pdf process.
Please find attached a lower resolution version which does not exhibit this problem (although some other images are of poorer quality).
Apologies for this oversight.
