CreoScitex Scan of an MC plate of M44 from the Harvard Plate Stacks
We scanned Plate MC39237, an 8x10 photgraphic plate taken on the
night of January 17-18, 1975, using a CreoScitex EverSmart Supreme
in its accelerated mode at 1200 bits per inch of spatial resolution
and 14 bits of intensity resolution. The resulting TIFF image contained
16 bits each of R, G, and B for 11470 x 9312 pixels. The means of the
three colors taken and written into a 16-bit FITS-format image file.
The WCSToolsimstar program
was used to find the positions of stars in the image, and
the WCSToolsimty2 program
was used to fit a world coordinate system to the image.
