As before, the software is available from our GitHub: https://github.com/thelondonsmiths/Solex_ser_recon_EN
The GUI looks the same as before:
The README file describes the additional features:
In general, I would recommend leaving the graphics turned off. Also, I would recommend (at least at first) to use "Save CLAHE.png only" because the number of files written quickly becomes large and confusing. Typically, I have found w = 2 for hydrogen alpha and w = 4 for calcium H works nicely (this assumes single binning on a 178MM; for double binning, a better setting would presumably be w = 1 for hydrogen and w = 2 for calcium).For no shift, leave the "Pixel offset" box at the default of '0'
Specify the output of a particular shift by entering a single number or particular values with commas: 'a,b,c,d,e'
For a range x to y with an interval of w, use colons: 'x:y:w'
If 'w' not specified, the default is 1 so 'x:y' will produce the range x, x+1, x+2, ... y-2, y-1, y
x, y, a, b, c can be positive or negative integers; the number w can only be a positive integer
Batch pixel shift processing of a batch of files is allowed
Typically, the images [-x, 0] look about the same as the ones [0, +x], so I would recommend (at least at first) to do pixel shift only in one direction to avoid a confusing accumulation of output files.
Below is an example of the output files done with the Solex website file 16_33_15 for hydrogen alpha done with the GUI settings show above:
Below is an example of a calcium H file I took recently:
Here are images from an old hydrogen alpha file I took assembled into a GIF. One advantage of this batch processing method is the shifts are all processed essentially identically so that making an animation is simpler (since the geometry correction is identical). These images were produced using the entry 0:8:2
Finally here is a GIF animation of the protuberance images done at -2 and +2 pixel shift. Presumably, the difference is an indication of Doppler shift.
