Blinking Script

[Carlos Milovic]

I made a very small change to the script. Now the statistics report (series anaylisis) writes the file without empty lines. This makes data import to a spreadsheet easier.

Thank you Carlos.

Gents,

From the latest version of the <Animation> script - at the following point in the code (line 1110 in v2.91 from Carlos) :-

Code: [Select]

            for (var c=0; c < dest.mainView.image.numberOfChannels ; c++)
            {
               var st = new Array();
               st[0] = parent.Images[i].mainView.id;

               if (dest.mainView.image.numberOfChannels==1) {st[1]=chanelName[3];Channel[3]=true;}
               else {st[1]=chanelName[c]; Channel[c]=true;};

               st[2] = String(parent.Images[i].exposure);
               st[3] = Number(r*s[i][c].mean).toFixed(n);
               st[4] = Number(r*s[i][c].median).toFixed(n);
               st[5] = Number(r*s[i][c].avgDev).toFixed(n);
               st[6] = Number(r*s[i][c].stdDev).toFixed(n);
               st[7] = Number(r*s[i][c].minimum).toFixed(n);
               st[8] = Number(r*s[i][c].maximum).toFixed(n);
               j++;
               stat[j]=st;

               for (var k=0; k < st.length; k++)
               {
                  if (hl[k] < String(st[k]).length) hl[k] = String(st[k]).length;
               }
            }

How can the script be modified to include extra information from the FITS Header?

Specifically, my new QHY10 imager provides a "Temperature" parameter, and I would like to be able to include that in the series analysis extraction.

I can see that the basic format is st[2] = String(parent.Images[j].exposure), but (as usual) I can't find out what alternatives there are for .exposure

Any suggestions?

Nikolai, I can envisage an upgraded script that provides a further dialogue box, where all of the available FITS Header parameters are presented to the user, and a check-box option is provided to allow users to select those data elements required.

Sorry, but you know me - I am always looking for 'something more' (I still have beer available, and Jedi Cookies )

Hi Niall
I did a quick inspection of the code, and the JS classes, but I can't find where the .exposure property came from! So I cannot help you there sorry.
(Oh how I love C++...)

[Niall Saunders]

What? Two Jedii - and neither of us know the answer?

I feel we ought to hand back the cookies Carlos

[NKV]

I did a quick inspection of the code, and the JS classes, but I can't find where the .exposure property came from!

JS ImageWindow.Properties.exposure
Also i see ImageWindow.Properties.keywords and i hope it's FITS keywords.
 

[Carlos Milovic]

Seems to... its an array.

Also, from ImageWindow.h (PCL, c++):

Code: [Select]

   /*!
      Obtains a copy of the %FITS header keywords currently defined for the
      image in this window. Returns true if this image has %FITS keywords.

      \param[out] kwds     Reference to a container that will receive a copy of
                           the %FITS keywords defined in this image.

      \sa SetKeywords(), ResetKeywords()
   */
   bool GetKeywords( FITSKeywordArray& kwds ) const;
So, I would say that it is highly likely that it contains the fits keywords, if they have been loaded.

[Niall Saunders]

Hi guys,

OK, I am a tiny step closer.

It also ocurred to me to apply the FITS Header process to an image, then to look at the History Explorer for that image. When I do that, this is the code that appears:-

Code: [Select]

// Start time: 2011/01/13 07:40:51 UTC
// Execution time: 1.280 s
var p = new FITSHeader;
with ( p )
{
   keywords = [ // name, value, comment
      ["SIMPLE", "T", "file does conform to FITS standard"],
      ["BITPIX", "16", "number of bits per data pixel"],
      ["NAXIS", "2", "number of data axes"],
      ["NAXIS1", "2612", "length of data axis 1"],
      ["NAXIS2", "3896", "length of data axis 2"],
      ["EXTEND", "T", "FITS dataset may contain extensions"],
      ["COMMENT", "", "FITS (Flexible Image Transport System) format defined in Astronomy and"],
      ["COMMENT", "", "Astrophysics Supplement Series v44/p363, v44/p371, v73/p359, v73/p365."],
      ["COMMENT", "", "Contact the NASA Science Office of Standards and Technology for the"],
      ["COMMENT", "", "FITS Definition document #100 and other FITS information."], // row 10
      ["BZERO", "32768", "offset data range to that of unsigned short"],
      ["BSCALE", "1", "default scaling factor"],
      ["EXPOSURE", "600000", "Total Exposure Time[ms]"],
      ["GAIN", "'10      '", "Analog Gain"],
      ["OFFSET", "'126     '", "Analog Offset"],
      ["TIME", "'00:23:45'", "Begin captuer time"],
      ["DATE", "'07/01/2011'", "Capture Date"],
      ["CAMERA", "'QHY10   '", "Camera model"],
      ["Temperature", "'-30.4   '", "Begin capture temperature"],
      ["Presion Time", "'0-23-45-281'", "Begin capture Presion Time"] // row 20
   ];
}

However, I still don't know how to get an extra parameter into the Animation script

I am trying to get the "Temperature" information (-30.4 in the example above) to be extracted into the statistics summary file. I thought it would be easy

[vetenskapsman]

Hi ... were you ever able to get the Temperature (or any other FITS Header information) extracted into the summary file?
That would be incredibly useful  8) 

I've been searching for a way to easily get FITS Header information for a batch of images (specifically EXPOSURE and
CCD-TEMP in my case) and the solution is oh so close with the Animation script.

Carlos, your ver 2.91 based on ver 2.8
Thank Yuriy Toropin for attention.
Latest (including Carlos modification) version 2.92 in attachment. Deleted. New version below.

By the way, I have a suggestion for improvement: could add an option to change the image that is displayed in the control? Also the rescalation in it is sometimes weird (not in the sense that it is wrong, but that some images are better represented as they were stored). Could you just use the same SFT settings as with the animation itself?

[NKV]

Could you just use the same SFT settings as with the animation itself?

You mean STF ? Done. See ver 2.93 in attachment  
Use autoSTF, autoHT, LinkRGB, ResetSTF&HT buttons to assign current image to control window.

But, i am going crazy... because i cant understand why code in line 968:

Code: [Select]

console.writeln("this.AutoSTF_Button dest.mainView.image.isColor ",dest.mainView.image.isColor);
         preview.assign(dest.mainView.image); //asign courent image to preview image
console.writeln("this.AutoSTF_Button preview.isColor ",preview.isColor);give strange result:

Code: [Select]

this.AutoSTF_Button dest.mainView.image.isColor true
this.AutoSTF_Button preview.isColor false
But, same code in line 1028 working good:

Code: [Select]

this.AutoHT_Button dest.mainView.image.isColor true
this.AutoHT_Button preview.isColor true
Any idea ?

Hi Nikolai,

I understand that you are currently working on other issues with the Animation script at the moment, but did you ever get a chance to look at the question I raised a few months ago (concerning the ability to include other FITS header information in the Summary Details listing and file output)?

How did you manage to 'find' the method for including the FITS data that you already include?

Juan - is there any way that you can help here? Nikolai's script is a wonderful tool, but has scope for improvement (as is always the case  )

My final (for the moment) 'wish' would be to be able to 'graph' the summary information without having to resort to the likes of MS Excel - have you ever thought about this as a task Nikolai (or anyone else for that matter)?

Hi Niall,

I described my idea how table views might be integrated into PI in http://pixinsight.com/forum/index.php?topic=2306.0 . Other applications I know do it this way, and I like it.

Hello Niall,
I hope to add FITSKeyword data during next week.
