Brick 0578m155 with RA,Dec center 57.8849, -15.5000. Brick pixel coords: 2144.8, 3034.4

These are postage stamps from the calibrated image files (so North is not necessarily up).

The "Weight" maps are 1/variance of the pixel values, including Poisson noise, so brighter areas will have relatively smaller statistical weight.

The "DQ" maps are flags raised by the Community Pipeline during processing for, eg, Cosmic Rays, bad pixels, etc.
