Apply functionality to apply livetime correction to science products

[hayesla]

It would be nice to have a way to apply the livetime correction to CompressedPixelData and Spectrogram data products. For example, we want to correct for it before a simple plot.

It looks like this is done for the quicklook data, but would need to be implemented for science data products. I imagine its just using get_livetime_fraction ? https://github.com/TCDSolar/stixpy/blob/main/stixpy/calibration/livetime.py#L96

I guess it would also make sense for it to be in .get_data()

stixpy/stixpy/product/sources/science.py

Line 539 in 95c342b

def get_data(

?

Any thoughts @samaloney ?

looking at it, it seems like there needs to be some mapping to triggers to detectors?

[samaloney]

Yea it's already done for the imaging but needs to be made a bit more robust and tested see here

stixpy/stixpy/calibration/visibility.py

Lines 160 to 165 in 95c342b

	# Map the triggers to all 32 detectors
	triggers = pixel_data.data["triggers"][:, trigger_to_detector].astype(float)[...]
	_, livefrac, _ = get_livetime_fraction(triggers / pixel_data.data["timedel"].to("s").reshape(-1, 1))
	pixel_data.data["livefrac"] = livefrac

I'm not really happy with the get_data method but not sure what to replace it with inside maybe a NDCube now which could make things easier but need to prototype it so should hold up adding it.
