[IDV #BVJ-740064]: Failure to open point data file

No worries...I blame ASCII text (CSV) files *laughs* It's easy to miscount the
columns.

> Greetings Roderick,
> 
> The issue with your header is that you forgot to define one of the columns
> in your csv file. Try this header:
> 
> (index)->(Latitude,Longitude,PM2_5,unknown,Time)
> Latitude[unit="degrees_north"],Longitude[unit="degrees_east"],PM2_5[unit="gram
>  m-3" missing="-99.0"],unknown[unit="" 
> missing="-99.0"],Time[fmt="yyyy-MM-dd-HH:mm:ss"]
> 
> Notice that there is an unknown parameter between PM2_5 and Time...you will 
> need to
> correct the name in the first and second line, as well as add the correct 
> unit and missing
> value in the second line.

> Cheers!
