  The New IRAM KID Array (NIKA) is a dual-band camera operating with frequency
multiplexed arrays of Lumped Element Kinetic Inductance Detectors (LEKIDs)
cooled to 100 mK. NIKA is designed to observe the intensity and polarisation of
the sky at 1.25 and 2.14 mm from the IRAM 30 m telescope. We present the
improvements on the control of systematic effects and astrophysical results
made during the last observation campaigns between 2012 and 2014.
