How to combine 1x1 binned and 2x2 binned data?
« on: 2012 February 18 11:42:35 »
I have a load of luminance data (1x1 binned). I have processed this luminance data ready to add the RGB data. I am currently taking this and binning the RGB 2x2. I can not see how, in PI, to get the resolution of the RGB to the same as the luminance. I can resample the RGB data from the resample menu, but I can only do one image at a time. I've tried a star align, but as the data is at different resolutions I can't do it.

Can someone please point me to the right menu? I have looked through them all, but can't see how to do it.

Try DynamicAlignment. In my opinion, StarAlignment  should also work. You may need to de-active the "use scale differences" option.

Georg is right, StarAlignment should register unbinned and 2x2 binned images without problems. You should disable the 'use scale differences' option (at the bottom of the star matching section) in this case. But even if you use it with default parameters (i.e. with the 'use scale differences' option enabled), SA's automatic probing feature should align your images in a second attempt.

If SA cannot align your images, I'd be interested in having a look at two of them to discover the cause.
