Array dimension error

[reseadmin]

This error may occur during the water vapor retrieval, if one tries to retrieve the water vapor from a spectral region where no image bands are available. So, one needs to check if there are bands in the 940nm or/and the 1130nm absorption region and only use the region which is available for the given sensor - if none is available one can not use the 'variable' water vapor option. In order to catch the error in a more comprehensive way, we'd have to check a sample data set at ReSe Support.

Thank you for your quick answer, The point is that the error happens if I do -not- use the variable water vapor option. If I, instead, activate it, the error disappears and processing continue as normal. Also, when the option is activated, the bands are chosen automatically by ATCOR (window 1 is 792.1-792.2, window 2 is 836.7-836.8 and wv absorption region is 817.1-834.0) and they do match a spectral region that's available in my image (it is sampled by a HySpex VNIR sensor with a spectral range between 403.08 to 992.9 nm. The automatically chosen channels on the image (as displayed by the ATCOR4 variable water vapor menu) are 123 for window 1 (792.06 nm) , 137 for window 2 (836.69 nm) & 131-136 (817.57-833.51 nm) for the wv absorption.
