TIR 2013-01: STIS NUV MAMA flats monitoring report
We analyze the STIS NUV MAMA flats collected during cycles 11, 17 and 19. The data collected within each cycles are normalized in a p-flat following two different methods. The two methods are compared and discussed. The evolution of the p-flat with time is presented, too, confirming the trend already reported by Brown et al. (2002).
