Concplot not showing source point

[darvil]

Hi,

Was following the tutorial to find the emission source from sensor readings here: https://www.ready.noaa.gov/documents/Tu ... _geol.html

The Concplot html I generated did not show the source location like in the tutorial pic: https://www.ready.noaa.gov/documents/Tu ... eol007.png

Could someone please help me understand what the issue could be?

I have also used the command line script provided here and the same thing happens : https://www.ready.noaa.gov/documents/Tu ... c_geol.bat

Apreciate any help on this. Thanks
