I used to use SMOKE3.5, but now I want to try SMOKE4.8.1. However, I found that 4.8.1 no longer supports the IDA format of 3.5. I would like to ask what order of changes have been made to the format of 4.8.1 for 3.5. Here are the original styles of my 3.5 and my own modified 4.8 point source format. Are they correct.

We suggest moving to the FF10 format as that is the format actively being used and supported.

The documentation for the FF10 POINT format is here:

[6.2.8. PTINV: Point source annual or average day emissions](https://www.cmascenter.org/smoke/documentation/5.1/html/ch06s02s08.html)

You should be able to use most of the same fields you had for IDA but SIC is no longer used.
