How to decode WE_WISH SSTV

JE9PEL, I explain a method of the decoding WE_WISH SSTV photo received ST2NH.
Because there is only a Japanese software and PDF file, I do not know whether
you can analyze it by a method to explain here properly in English. Please test.

(*) In the PDF file writing on how to use WE_WISH decoder, the way of
    the temperature setting seems to include some error. In other words
    the ruggedness of the 3D image of SSTV which I explained in my home
    page might be against all so far. Please wait for a while, because
    I am asking GS a question now.

(**)I corrected here the explanation of the last page in the PDF file of
    WE_WISH SSTV. This was comfirmed in Ground Station as above.


 1. You will get a clean red and a yellow photo of the infrared signal using
    MMSSTV. Save this image as the BMP file. And you will notice some curved
    lines at the center of the image. I do not know what it is.

 2. Install Decoder and PDF file from Japanese homepage of WE_WISH GS.
    https://sites.google.com/site/jq1ziijq1zij/home/shou-xin-fang-fa
    https://sites.google.com/site/jq1ziijq1zij/english, English page

 3. Set BMP file which you saved first in the column of this decoder.

 4. Set two CFG file 'AMB20-OBJ20_Cal.dat' and 'AMB20-OBJ40_Cal.dat' etc.
    Input temperature value in two columns of this decoder, and run it.
    See the next image for example.

 5. The CSV file is generated in the folder automatically.
    It is 'st2nhstv_OUT.csv' for example.

 6. Open this CSV file using a tool Graph-R 2.30 'GraphR.exe'.

 7. You will decode them as follows.

 You can see the gradient boom.         After correction by JA0CAW

Dear Mineo san,
I received a new SSTV image from We-Wish. Can you explain me,
what we see in the image?

I know it's an infrared or thermal image - but of what.
Is it inside the cube or outside to earth?
I did not found any english informations about that.
Maybe you can help me, please?

Thanks ! 73 Dewa,
Mike, DK3WN

Dear Mineo san,
I managed to get the temperature gradient.
I forgot to type in the values for H and L rangec

I should better learn japanese language, hihic
