For future PCC users, I strongly recommend using the SDSS-DR9 data instead of the APASS whenever possible. The SDSS data are acquired with a 2.5m telescope and the APASS data with a 3.15cm.  Also, the SDSS folks are more experienced. Additionally, the APASS staff have freely admitted that some of their data are problematic.

I recently encountered a Southern Hemisphere field-of-view where the APASS data had obviously highly inaccurate (b-v) values. Also, the Sloan g' and r' filters produced poor RGB color correction. In the Northern Hemisphere, the APASS data have always agreed with the Sloan for color correction.

BTW Juan, will the PCC user interface return the RGB values used for the pixel math? I would like to compare with my results. I have no doubt that the PI routines are more sophisticated than eXcalibrator's white-star and linear regression.  Also, with direct access to plate solving, the PI process will be easier to use.

But will the results provide a significant difference in the final color? It can take a surprisingly large change in RGB factors to be noticeable in the final image.

Like I said earlier, I am a PixInsight user and find the program exceptional and powerful. I'm looking forward to taking PCC for a spin.

Regards,
Bob

Hi Juan
Very exciting features for next release


If you need some "direct integrated" images (modded DLSR A7s) with gradients have more images to test new algorithms, let me know, it will be a pleasure to help.


Anyway, again, again, many thanks for your work.

I still don't dare to anticipate a release date. It should happen during the first half of June...
Looking forward to it  ;)

If you find time, I have a feature request: O:) ... many webserrvice api use content type json. Would be great if the NetworkTransfer could support json as content types as well.

Btw, what is the javascrip member/method for the EnablePasswordMode method of the pcl::Edit class. Couldn't figure it out ...

Hi Klaus,

Thank you :)

NetworkTransfer::ContentType() will return whatever the server has reported as content type for the latest download operation. Unfortunately, in many cases servers and/or network applications are not properly configured and report invalid content types such as text/plain for JSON data, instead of application/json. There is nothing we can do to solve this.

Edit::EnablePasswordMode() is what you are looking for.

By the way, if you are requesting passwords using PCL controls such as Edit, consider calling String::SecureFill() to wipe out the password securely when it is no longer needed. The corresponding string in the server-side control is always destroyed securely when the password mode is enabled.

Oh, sorry, I didn't read your post correctly (too many things in my head I guess). The PJSR Edit object also has a passwordMode property:

Boolean Edit.passwordMode

which works just as pcl::Edit::EnablePasswordMode().

Hi Philippe,

Thank you so much.

Having more images for testing is always a good thing, so yes, if you can upload some of them I'll appreciate it ;)

My problem is that I want to send data in JSON form via POST request. With curl I would express it as follows:

curl -H "Content-Type: application/json" -X POST -d '{"user":"xyz", "password":"XYZ"}' url

AFAIK the POST operation of the NetworkTransfer POST method only send form data ...

Hi Klaus,

This is not possible with the current version. I am going to implement support for custom HTTP headers in version 1.8.5 (hopefully I'll upload a new development version for Linux today, along with a new version of PCL).

This is great news! Can I use/download such a development version? Then I can also continue on my telescope pointing stuff ...

Are we there yet? ;-)  :P

(In all seriousness I'm about to process an image and I'd like to reprocess one I'm not fully satisfied with, and I'm sure this new release would help. Hence I'm pondering whether or not I should wait for it ^^ )
