CFCN-DT(1) Calgary possible error

There appears to be a problem with the antenna file associated with CFCN-DT(1) Calgary. The coverage shown under "Pending" for Channel 29 does not resemble what it should be. It shows some areas of Calgary being served with practically no ERP whatsoever.
As a reference, it should look more like the entry for CFCN-DT on Channel 36 listed under "Pending".
Thanks for looking into it.

The antenna pattern ID for this transmitter is listed as number 7858, and it looks like that antenna pattern entry is incomplete. Most antenna patterns specify the relative power output in all directions (360 one-degree increments), but the data for antenna pattern 7858 only covers angles between 0 degrees and 89 degrees.

It looks like someone accidentally copied the vertical beam pattern data and put it where the azimuthal radiation pattern ought to be.
