Software Error PI in Function "HDRComposition"
« on: 2010 May 11 11:28:11 »
Hi all,

I tried HDRComposition with some (debayered and pre-aligned) Fits-Files, which were made with a Canon EOS 450d.
Please find attached a screenshot of the data entered in the HDRComposite function.
Here is the log of the processing console:

[high range problem: no samples between 0.6-0.8]

I think that this is the source of the problem. It says that the debayer_cal_img_1943_c_r_1.fit file has no pixel values in that range, so the script is unable to get to the next step.

Please try this:
a) Make sure that all your files are in exposition time order.
b) Open them, and check that they cover (almost) the whole normalized dynamic range. It is supposed that intermediate, and the loger exposured frames will have saturated data (i.e. = 1). Also they should have been bias substracted.

Also, if you have a series of images with the same exposure time, it is better to integrate them, and then use the "master light" for that given exposure time.

Thank you Carolos for your kind replay,

I did the following:

1. I sorted all  pics in order of ascending exposure time.
2. Bias Frames are already subtracted.
3. I used the application form as described in the attached screenshot.

Now I still got 2 error messages:
*** Warning [156]: /home/chris/PixInsight/src/scripts/HDRComposition.js, line 171: assignment to undeclared variable point
*** Error [000]: /home/chris/PixInsight/src/scripts/HDRComposition.js, line 85: Assersion falied: Error calculating intensity map! [high range problem: no samples between 0.3-0.9]

The second message as before. The first error message is new to me.
Can I check the dynamic range of a frame in PI with a special function ?

Thanks !!
Christoph

Hi  :)

Yes, use the Histogram. You may move the sliders of the black and white points to see how many pixels are at either side.

OK!  :)

It seems, that after applying the Histogram function to the "problem FITS files", the HDR Combine seems to work.
But - also I receive a result, I got the message
*** Warning [156]: /home/chris/PixInsight/src/scripts/HDRComposition.js, line 171: assignment to undeclared variable point

This seems to be nothing serious, but may be interesting to you :
