 ## Overview
 
-This bundle supports ground-based long-wave infrared (LWIR) hyperspectral imaging for heat-assisted detection and ranging. It combines six scenes from the [DARPA IH Dataset](https://www.kitware.com/ihdataset/) with a shared U.S. Standard Atmosphere (USSA) spectral pair: horizontal-path attenuation coefficients and a ten-angle downwelling-radiance basis.

-The atmospheric products are a frozen copy of the `data/` directory from [Ozone-Cues (LWIR absorption-based ranging)](https://github.com/unaydorken/Ozone-Cues-Mitigate-Reflected-Downwelling-Radiance-in-LWIR-Absorption-Based-Ranging/tree/main/data). All six IH captures are daylight, near-surface scenes. For clear-sky conditions with similar air temperatures, recent work on this problem finds that site-to-site differences in downwelling spectral features are small compared with other inversion errors, so the six cubes share one USSA atmosphere rather than a per-scene sounding.

 The ENVI cubes are too large for GitHub. The image build fetches this same layout from the frozen Hugging Face dataset [dccc2025/tmp_dataset_hadar](https://huggingface.co/datasets/dccc2025/tmp_dataset_hadar) and checks SHA256. That fetch is pinned to a commit (not a moving `main` branch) and is not a live scrape of Kitware.

 1. **Wavelength alignment.** LWHSI1 cubes have 256 bands starting near 8.06 µm. LWHSI2 cubes have 250 bands starting near 6.84 µm. The downwelling `lambda` grid is a 256-channel LWIR window and does **not** automatically match every scene. Interpolate or band-select every spectral product onto the scene wavelength grid before combining them.
 2. **Separate attenuation grid.** `attenuation.npz` has its own `lambda` axis, offset from the downwelling grid. Resample `attenuation` onto the scene grid before using \(\tau(d)=10^{-\alpha d/10}\).
-3. **Shared atmosphere.** One USSA attenuation cube and one ten-angle downwelling basis are used for all six scenes. This is a documented approximation for clear-sky, similar-temperature collections, not a claim that the real soundings were identical.

 4. **Downwelling basis.** Treat the ten columns of `downwelling_res` as a fixed, ordered angular basis; do not permute them. They are not the delivered single-band texture map `X`.
