Next: Input and Output Up: CCD Reductions Previous: Basic Reduction Steps . Clearly, the most vital part of the CCD package is the combining of multiple exposures of calibration or science frames into a master frame. Therefore, before the actual processing is done, the calibration frames should be created first. The command that takes care of combining the calibration frame in the CCD package is COMBINE/CCD . ...

The above process keeps the # of protons and the # of neutrons in the early Universe constant. This is extremely important and will result in a testable prediction later. Remember, a free neutron (one that is not bound in an atomic nucleus) will decay into a proton + electron (+ anti-neutrino) in about 900 seconds. ... During this epoch, the proton-to-neutron ratio is 1.0 . ... The Universe consists of protons, neutrons and electrons plus a photon background and a neutrino background. ...
