Magellan
A forward marine magnetic modeling program

A to do List for next versions of Magellan

1. Add artificial bathymetry - Currently the user needs a data file with bathymetry. A feature has to be added so the user can run magellan with out a data file. We would use the equation of seafloor deepening with age for this.
2. Add option to specify distance between calculated points - Currently Magellan only calculates the model where data points are, i.e. if a user has data points with 3-km spacing, Magellan will calculate data at this point which will leave out small reversal periods. A feature where the user can choose the spacing between calculated points would be good. There might be a problem with the bathymetry since we would 'ideally' have to spline in between bathymetry points to get a depth value at the artificial point Magellan creates (this is how the algorithm works, the bathymetry and data lists have to be the same length). Another way to approach the problem would be to use the nearest bathymetry value, since it doesn't change drastically over small lengths (this would make the problem way easier).
3. Allow choice of axis - Create the options -x<lower/upper> and -yb<lower/upper> [for the bathymetry] and -ym<lower/upper> [for the model] so the user can choose the upper and lower limits of the axis.
4. Save calculation output in a file - Save the parameters needed to create the figure so the user doesn't have to run magellan again just to get the figure. This could be useful if the user want to plot the data elsewhere, i.e. using GMT.
5. Calculate and subtract the regional field from data collected - In current version the user has to remove the regional fied first before using Magellan. Magellan will take care of this for the user in the future.
6. Create a graphical user interface - Magellan is currently command line based. A graphical user interface will be developed in the future once the items above have been implemented.
