The function available here is due to Dave Green (MRAO) and does a helix in OFM colors which is monotonically increasing in perceived intensity. It is being published as: Green, D. A., 2011, Bulletin of the Astronomical Society of India, 39, 289. Press button A to toggle the direction of rotation of the helix. Press button B to increment the number of rotations by 0.5 - it starts at 1.5 and reverts to 1.0 after exceeding 4. Press button C to increment the saturations by 0.2 - it starts at 1.0 and reverts to 0 (black & white) after 2.0. (Saturations over 1.0 cause some levels to be clipped, but the perceived saturation still increases all the way up to 2.0.) The cursor X position controls the starting color and the cursor Y position controls the gamma of the color curve. Press button D to exit. Adverbs: TVLEVS....Specifies the maximum intensity expected for the sum of all visible, overlapped images. Has always been n x max in one image (now 2046). < 2046 => 2046. DOPRINT...= 1 => display the helix parameters as they are changed during the interaction =-1 => display the parameters once at the end = 0 => no display of parameters ----------------------------------------------------------------
