Spikes and AIA data

The level-1 AIA data that are available through the JSOC or VSO have already been "de-spiked", i.e., cosmic ray hits have been removed. A small fraction of the removed pixels, however, are actually real solar features.

The paper Young et al. (2021, Sol. Phys.) investigates the fraction of spikes that are due to solar features using a 171 A dataset. The IDL software developed for this article are available on GitHub.

Additional information about AIA spikes is given on the Hinode/EIS wiki.
