Dark circles in Radio

  • Milkybear by Milkybear

    There are two dark circles in the radio image below the largest IR object. Is it any thing interesting?

    No, these are just regions which happen to have low values by chance (ie, this is noise). When we map the measured data values to colours, such low values become black, everything brighter than some maximum value becomes white, and in between things have blue hues.
