 <p>From a review paper:</p>
 <blockquote>
 <p>"Several methods were proposed to overcome the lack of inter-satellite calibration. These include the invariant region and the quadratic regression method proposed by Elvidge et al. [23], the second-order regression and optimal threshold method proposed by Liu et al. [24], and a power-law regression method proposed by Wu et al. [25]. Although studies based on these calibration methods showed performance improvement after the rectification [24,25], the assumption that the nighttime light remains stableover time in a particular area requires a careful choice of the invariant region manually."

 <p>The calibration models do not include regression coefficients for all of the yearly products. In which case, the module will fail and inform with an error message like:</p>
