| cftype | str | The type of filtering that is applied to remove the continuum. "weight" refers to the weighted median, which uses the calculated zlevel sky as the weight. "median" refers to a rolling median filter with a nested small uniform filter. The weight option provides a better result, but is much slower (an additional 10 minutes on a single exposure) and should only be run in the complete sky subtraction case. | |
| cfwidthSP | float | Window size for the continuum filter used to remove the continuum features for calculating the eigenvalues per spectrum. Smaller values better trace the sources. An optimal range of is typically 20 - 50 pixels. | |
| cfwidthSVD | float | Window size for the continuum filter, for the SVD computation. | |
| clean | int | NaN correction, this is a boolean set to True as default | |
| extSVD | str | An optional parameter that allows the input of a externally calculated eigenbasis as well as a zlevel. | |
| mask | str | (only used with the SVDoutput method) A 2D fits image to exclude regions that may contaminate the zlevel or eigenspectra. | |
| n_components | int | no description available | |
| ncpu | int | no description available | |
| nevals | float | number of eigenspectra per, list of the number of eigenvals to include, set as 0 by default | |
| pca_class | str | no description available | |
| skycubefits | str | description todo | |
| varcurvefits | str | Path for the optional output of the explained variance curves. | |
| zlevel | str | This option is used to define the method for determining the zeroth order subtraction of the sky. This is used to remove any systematic sky feature that exists over the whole field. Options are median, sigclip, and none. The none option should only be applied when ZAP is applied to enhance a previous sky subtraction. | |
