 | <step>.nchan | int | 1 | Number of channels in each channel block, for which the solution is assumed to be constant. The default is 1, meaning one solution per channel (or in the case of constraints, fitting the constraint over all channels individually). 0 means one solution for the whole channel range. If the total number of channels is not divisable by nchan, some channelblocks will become slightly larger. | | <step>.nchan | int | 1 | Number of channels in each channel block, for which the solution is assumed to be constant.

When unequal to 0, all stations within the given distance from the reference station (0) will be constraint to have the same solution. | | <step>.coreconstraint | double | 0 | Distance in meters.

-| <step>.antennaconstraint | list | [] | A list of lists specifying groups of antennas that are to be constrained to have the same solution. Example: "[[CS002HBA0,CS002HBA1],[CS003HBA0,CS003HBA1]]" will keep the solutions of CS002HBA0 and 1 the same, and the same for CS003. |+| <step>.antennaconstraint | list | [] | A list of lists specifying groups of antennas that are to be constrained to have the same solution.

 | <step>.smoothnessconstraint | double | 0 | Kernel size in Hz. When unequal to 0, will constrain the solutions to be smooth over frequency by convolving the solutions with a kernel of the given size (bandwidth).
