s.outputs.XX<TAB> doesn't work

[Mengmeng Yang]

Hi Robin,

I want to print and plot the outputs of 6S including at least apparent reflectance, Rayleigh reflectance, and transmittances for the whole wavelength range of an airborne sensor. So I tried to check the output data names by running s.outputs.tra<TAB> and s.outputs<TAB>. For the former running, I got nothing, and for the latter one, I got just s.outputs. But when I ran s.a<TAB>, I got the same results as that in the Py6S document.

So I wonder why s.outputs.tra<TAB> and s.outputs<TAB> doesn't work on my PC (ubuntu on mac os)? And how to check the output names of SixS()?

Thank you in advance.

Kind regards,

Mengmeng.

Hi,

You need to make sure you've run the 6S model with `s.run()` before you try and look at the outputs - the autocompletion won't work until the model has been run. Also, to get a full list of all of the possible names that can go after `s.outputs` you need to type `s.outputs.` and then press tab (notice the trailing dot).

To get a full list of all of the output names, you can run `dir(s)` (making sure you've run `s.run()` first).

Hi Robin,

Thank you for your reply. Now I can get a full list of all of the possible names. But when I ran dir(s) after running s.run(), I got some names which seemed to be not like the output names. 

So I wonder dir(s) is not the code I should run?

Kind regards,

Mengmeng.

Hi,

Yes, dir gives you all of the attributes on a Python object. Some of them are internal Python attributes, which are signified by starting with underscores.

Also, you should be running `dir(s.outputs)` rather than `dir(s)` - sorry, that was my mistake in my last email.

I see, thanks.

Hi Robin,

I didn't find the description of the output names. So I am not sure what are 'atmospheric_intrinsic_reflectance' and 'pixel_reflectance'? What is the difference between 'apparent_radiance' and 'atmospheric_intrinsic_reflectance'? Is 'reflectance_I' the atmospherically corrected reflectance with taking into account polarization effect?

It may be possible to understand the meaning of the output names from the 6S document, however, I have not understood that document well yet. So could you answer my questions above?

Thank you in advance.

Kind regards,

Mengmeng.
