README file for LANDSAT-9 Thermal Infrared Sensor filter functions (TIRS)

June 2023

Filters were obtained from file landsat official web site:
http://landsat.gsfc.nasa.gov/


SRF pre-processing:

* 1 Extract data from MS Excel file

* 2 Convert wavelength to wavenumbers

* 3 Name band files
 - channel 1 is 10.83 um
 - channel 2 is 12.04 um

There was no need to truncate the files
