Why do I see a circular coverage distribution chart when I view others’ data but not when I view my own? I thought maybe it was because I joined recently, but since then I’ve noticed the circular coverage distribution chart for people joining after I did.
Since the observer location keeps drifting, I’m also wondering if the chart is based on the drifting position or on the real position.
I read in another post that this chart shows up when you reach 25000 positions reported. So a receiver with many positions received will start showing up faster than one receiver from a “sparser” sky. Mine showed up in a day.
The colors are just determined by the number of positions. Each block on the chart represents a certain distance range (e.g., 150-200nm) within a certain direction (e.g., SW). If you hover over a specific block on the chart, a pop-up will tell you how many positions were seen in that distance range in that direction.
The color of the block is determined by this number, with the color trending towards a dark red to indicate the regions of heaviest activity and a very light blue to indicate regions of the least activity.
Both of these feeders have similar positions reported (granted 25% of mine S at <50nm) however the remainder should produce different colour schemes. I am PP1 in the above URLs. You can see different colour schemes for the SW position with 3218(PP1), 2314(PP2) and 2431(PP3) positions respectively.
