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 following corrected image for example.
    http://www.ne.jp/asahi/hamradio/je9pel/st2nhtv1.png

 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.

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…

I should better learn japanese language, hihi…

73 Dewa,
Mike
