Data space and image space

In this thesis, I refer to data space as the un-migrated space. This means data as a function of time. I consider two main sets of data: source gathers and CMP gathers. The first are function of the source coordinates, offsets and time while the second are function of the CMP coordinates, half-offsets and time.

I will refer to image space as the domain of migrated data. In particular, data migrated in depth. In image space I consider two main datasets: Subsurface Offset Common Image Gathers (SODCIGs) and Angle Domain Common Image Gathers (ADCIGs). In this thesis I will use exclusively wave-equation migration algorithms.
