In this case, an emission line was identified incorrectly as a CR on both images. Pressing c followed by by y copies this region to the other image, and pressing q terminates the marking. Next, the user is given the option of manually editing the bad pixel files to correct any input errors before effecting the fix. Now bad pixels are interpolated across and the resulting images displayed in frame buffers 3 and 4. Compare buffers 1 vs. 3 and 2 vs 4.
Processing is completed.
An image display tool with multiple frame buffers, such as Ximtool or SAO-tng is required.
