FITS WebQL v4 (beta) was released. New feature "Cube Slicer" is abailable for ALMA/Nobeyema FITS Cube Data. Usage
FITS WebQL v4 (beta)
New feature: FITS Cube Slicer
FITS cube slicer displays the image at a frequency channel specified by a cursor. The image is updated in near real time in accordance with the movement of the cursor.
Move the cursor neare of the bottom axis, and slide it to the left or right side (along frequency axix).
In order to display the zoom-in image, push the shift key at the location where you want to see, and move the cursor to the bottom axis holding the shift key. After that you can release the key and move the cursor along the frequency axis.
