Detailed Description
The Gaussian image is defined by an axis size and overall flux normalization. Note that this is not derived from model_image because there is no meaning for the position angle.
Parameter list:
- parameters[0] ... Total, integrated flux in Jy.
- parameters[1] ... Standard deviation in radians.
- Warning

virtual |
Returns closure amplitude computed from the image given a datum_closure_phase object, containing all of the accoutrements. While this provides access to the actual data value, the two could be separated if necessary. Also takes an accuracy parameter with the same units as the data, indicating the accuracy with which the model must generate a comparison value. Note that this can be redefined in child classes.
Implements model_closure_amplitude.
|
virtual |
Returns closure phase in degrees computed from the image given a datum_closure_phase object, containing all of the accoutrements. While this provides access to the actual data value, the two could be separated if necessary. Also takes an accuracy parameter with the same units as the data, indicating the accuracy with which the model must generate a comparison value. Note that this is redefined since the closure phase of Gaussian images is identically zero.
Implements model_closure_phase.
|
virtual |
A one-time generate function that permits model construction prior to calling the visibility_amplitude, closure_phase, etc. for each datum. Takes a vector of parameters.
Implements model_closure_amplitude.
|
inlinevirtual |
A user-supplied function that returns the number of the parameters the model expects
Implements model_closure_amplitude.
|
virtual |
Returns visibility ampitudes in Jy computed from the image given a datum_visibility_amplitude object, containing all of the accoutrements. While this provides access to the actual data value, the two could be separated if necessary. Also takes an accuracy parameter with the same units as the data, indicating the accuracy with which the model must generate a comparison value. Note that this is redefined to accomodate the possibility of using the analytical computation.
Implements model_visibility_amplitude.
