I used the Mosaic to New Raster tool to create a single raster of several adjacent tiles (they do not overlap). They are 8-bit TIFs and I chose 1 band (input is 1 band). I expected to see the cell count of the mosaic would be the total of the inputs. Instead, the resulting attribute table is a copy of the values from just one of the inputs.
I know I've done this before and it worked fine but I can't figure out what I'm doing wrong this time. I also did try creating a mosaic from the image analysis window but it's creating a 3-band raster without a table and I don't see where I can control that.
