The input for this function is the raster. There are no other parameters for this function because all the information is derived from the input's properties and key metadata (bands, data type, and sensor name). Only imagery from the Landsat MSS, Landsat TM, Landsat ETM+, IKONOS, and QuickBird sensors are supported.
If you want to apply just the greenness variable, you could use Raster Calculator.
Add TM1-5 and TM7 to ArcMap.
Open Raster Calculator (Spatial Analyst) and write the expression similar to that given below:
Float (((-0.2728)*TM1) - ((0.2174)*TM2) - ((0.5508)*TM3) + ((0.7221)*TM4) + ((0.0733)*TM5) - ((0.1648)*TM7))
Note: Replace "TM1-5" and "TM7" with the corresponding band names.
