Missing Rw in polymer output for MODIS

Hi,
I am working on applying Polymer to MODIS aqua data.
At this point I am using the l2gen processor to create the L1C file that is required in polymer.
I use the recommended l2prod list as suggested in the readme (l2prod="rhot_nnn polcor_nnn sena senz sola solz latitude longitude").
The L1C file includes all the spectral bands of MODIS. However, after running ./polymer_cli.py the output data does not include all the Rw for all the spectral bands in the L1 input.

Am I missing an optional command that specifies which product to output?

Appreciate the help.

Thank you,
Jonathan Sherman

Edit- I added a screenshot of the products in the L1C file and in the Polymer L2 file. (The bands I am interested in are the visible spectrum bands up to 748nm)

Dear Jonathan,

Apologies for the late answer. The L1C file should be fine.
But you can indeed specify which bands you are interested in, with the following argument:
run_atm_corr(..., bands_rw=[412,443,469,488,531,547,555,645,667,678,748,859,869,1240]) (or just a subset of these bands)
Please note that the MODIS land bands, like 469, are only supported in the latest version v4.14.
Cheers,
François
