A near infrared variable star survey in the Magellanic Clouds: The Small
  Magellanic Cloud data
  A very long term near-infrared variable star survey towards the Large and
Small Magellanic Clouds was carried out using the 1.4m InfraRed Survey Facility
at the South African Astronomical Observatory. This project was initiated in
December 2000 in the LMC, and in July 2001 in the SMC. Since then an area of 3
square degrees along the bar in the LMC and an area of 1 square degree in the
central part of the SMC have been repeatedly observed. This survey is ongoing,
but results obtained with data taken until December 2017 are reported in this
paper. Over more than 15 years we have observed the two survey areas more than
one hundred times. This is the first survey that provides near-infrared
time-series data with such a long time baseline and on such a large scale. This
paper describes the observations in the SMC and publishes a point source
photometric catalogue, a variable source catalogue, and time-series data.
