    136136You should check that the peak level in the star image is not above appoximately 200 adu (255 is the max, but the peak can vary from frame to frame). A tool that can be used for this is bibtool, which is set up to run on the (default) bmp format images from the vimbaviewr gui. Here is an example of how we might view and measure the image named 20191029_0910_9.bmp:

    138   [astronomer@mcs Bib]$  biblook 20191029_0910_9 bmp N
     138  [astronomer@mcs Bib]$  biblook /hetdata/data/ImageQuality/20191029/Bib/20191029_0910_1017.bmp N
     139or, if you are inthe working directory:
     140   [astronomer@mcs Bib]$ biblook /hetdata/data/ImageQuality/20191029/Bib/20191029_0910_1017.bmp N
    139141}}}

This was done in case the user wished to record other image formats (like tiff). The user places a circle marker around the star and enters a return . At that point the user is shown a single line of values. The header indicates that the second number from the end of the line is the peak value. Here is an example:
