Version 1 VNIR Hyperspectral Reduced Data Record (VRDR) map tiles include 90 spectral channels across the CRISM VNIR wavelength range and have been assembled primarily from ~90 m/pixel VNIR hyperspectral observations, downselected for data quality and low atmospheric opacity, with corrections applied to mitigate noise in the data, calibration artifacts, and effects of spatial and temporal variations in atmospheric opacity. The VRDR map tile product suite includes corrected spectral data, spectral summary parameter products, browse versions of the data, and information that provides traceability to the source observations.

Hi Tejay,   I've spoken with the CRISM team about this issue, and they let me know that they updated the formulations of the BD1900_2 and BD1900R2 parameters in order to make the products less noisy. The preferred formulations these parameters for hyperspectral data are now: BD1900_2: just BD1930 with slopes anchored at 1850 and 2067, with kernels of 5 for all wavelengths BD1900R2: as listed in the SIS except with slopes anchored at 1815 and 2132, with kernels of 5 for the anchors and 1 for all other wavelengths I'll be working with the CRISM team to make sure the documentation gets updated to reflect this.   As an additional note, many of the parameters have slightly different formulations for hyperspectral vs. multispectral data. In most cases, the main difference is kernel width (multispectral products always use a kernel width of 1, since there are fewer wavelengths available), but the following products all have other differences: RPEAK1, BDI1000VIS, BDI1000IR, VAR, BD1500_2, BD1900_2, BD1900R2, BDI2000, BD2100, BD2100_2, BD3400, BD3400_2. I'll be working with the CRISM team to make sure these differences are fully documented in the SIS.   Best, John

Hi Tejay,   For MIN2200 - yes, that currently uses a kernel width of 3 for R2210. That looks like a typo in the documentation (they have R2120 listed twice), so I'll pass it along to the team to get fixed.   For BD1900R2 - I'll check with the CRISM team on what kernel widths were used to generate the SU product. The calculations that I can see suggest a kernel width of 5 for the two anchor points and a kernel width of 1 for all the others, but it looks to me like the kernel width of 3 you suggest does a slightly better job of reproducing the data in the SU product.   John
