This series of delay-doppler radar images of the asteroid 4769 Castalia (also known as 1989 PB) were taken at approximately 2 minute intervals on 1989 August 22 at the Arecibo Observatory. ... These images have been stretched to look decent on a browser, rather than for accuracy. ... Thus these images have a frequency resolution of 0.24 Hz (~40 m), and a frequency sampling of 0.12 Hz, but the signal to noise ratio should be 2 times worse, as only 6 looks can be summed. ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...

Including this sixth coordinate axis provides us with a hierarchical (multi-resolution) CCT. ... Various 2- D slices through the multiresolution CCT may correspond to useful tilings of the TF plane with true parallelograms (true to the extent that the DPSS define a truly rectangular region in the TF plane). ...
