how to obtain rhos_859 in Seadas

[zxc1973258]

Hello，
I used Seadas_8.0.0 gui in linux to process Modis date.Now I have trouble running l2gen. I want to obtain rhos_859 value.But there are just rhos_421 to rhos_678 in Products.
Any thoughts or suggestions would be very helpful!
Thanks,
Xm Liu

In l2gen GUI, there is a products tab. In the "product selector" section, make sure you unwind rhos and check the rhos_859 box

Thank you xuanyang02.
I choose all rhos,but there is just rhos 412 to 678.I used modis_1A to process Modis L0 data.Then I used modis_GEO and modis_L1B to get A2017168053000.L1B_LAC data.

In the "Selected Products" section on "Products" tab, are you able to change rhos_vvv to rhos_nnn?

I tride to input rhos_nnn，but then it changed to rhos_vvv again.I can not change it to rhos_nnn.

Sorry that this is a bug, we'll try to fix it for the next release.

For the time being, here is a workaround:

Click "Save Parameters" in the "Parfile" section on the "Main" tab, and save the Parfile in /home/xm/modis2017 as l2gen-tmpParFile20210607.par.

Use a text editor (vi or emacs) to open l2gen-tmpParFile20210607.par, and change rhos_vvv to rhos_nnn.

In a terminal, in the directory /home/xm/modis2017, do
"l2gen par=l2gen-tmpParFile20210607.par"
