Bleh, a whole day's work dedicate to new delining methods and testing. Very unrewarding. However, there are results that I need to FINALLY prove and show tomorrow: 1. amplitude suppression + phase preservation is a good alternative to zeroing/scrambling or replacing with noise 2. line fitting is effective but slow 3. Assuming a line profile and suppressing is nearly as effective as line fitting 4. scan-by-scan is less effective than observation-by-observation for fitting (but it's not clear if that holds for other methods)
