I think this has been mentioned to you before:
*The most important rule in data processing is look at your data.'*---
T*he 2nd-most important rule is* *read the documentation of the project.*
Note: It is not ncl-talk's job to read the documentation. It is your job.

Variable: MIR
Type: *ushort*
Dimensions and sizes: [DIM_000 | 1] x [DIM_001 | 1616] x [DIM_002 | 1618]
* lab_radiance_add_offset *: -0.00413433
lab_radiance_add_offset_gsics : -0.0110259
lab_radiance_quad : -1.31797e-07
lab_radiance_quad_gsics : -1.88751e-07
*lab_radiance_scale_factor *: 0.000281346
lab_radiance_scale_factor_gsics : 0.000402925
I *speculate* that to get correct values you would have to use something
like:
MIRF = MIR***MIR@*lab_radiance_scale_factor + MIR@*
*lab_radiance_add_offset*
or
MIRF = *(*MIR* + **MIR at lab_radiance_add_offset**)**MIR@
*lab_radiance_scale_factor*
or
* ????*
Again, this is your responsibility.
Good Luck
