Does anyone have calibration file for ECM8000 microphone that I can use with ETF 5?

Isn't the point of buying a measurement microphone that it should be flat and require no corrections?
I ask that honestly, since I have an ECM8000, and thought that by definition it should be flat (or reasonably so, say +/- 1dB from 20 to 20 kHz).

Even the $250 mic/preamp sold at http://www.etfacoustic.com/micpreamp.html comes with a calibration file.

Here's the 'generic' Behringer file that comes with TrueRTA. Pretty flat for such an inexpensive mic. It does roll off a bit above 15K.

The calibration file for RS meter from ETF 5 looks different and has 6 columns. http://www.etfacoustic.com/Software/RSAnalogueSPL.zip
I wonder how I can convert the above info to the below format.
