Next: How to get Up: Introduction Previous: Introduction . ... However, we cannot make all our observations at the same time, or at the same place in the sky. ... To do this, we must distribute the observations so that the main independent variables (such as airmass, star color, and instrumental temperature) are uncorrelated with each other. ... As some (like temperature) are inherently likely to be correlated with time, it is doubly important that others (like airmass) be uncorrelated. ...
