- kinms_fitter.transformClouds.transformClouds(inclouds, posAng=90.0, inc=0.0, cent=[0.0, 0.0], sbRad=None)¶
Transforms skySampler cloudlets for use in KinMS.
Calculate the galaxy co-ordinates of clouds from the sky plane. This MUST be used if any of the following conditions are true: inc != 0 posAng != 90 cent != [0,0]
This exists as a stand-alone routine since an MCMC fit to the galaxy will likely need to run this every step, and the sampleClouds routine is computationally expensive ============ Inputs:
clouds: np.ndarray The output of the sampleClouds array [x,y,I]
posAng: 0=<float<360 The position angle of the galaxy major axis, measured from the y-axis of the cube
inc: 0=<float<90 The inclination of the galaxy, with 90 being edge-on
cent: [float,float] The photometric centre of the galaxy relative to the centre of the cube
Outputs:
clouds: np.ndarray Positions and intensities of particles [x’,y’,I]
