HSC-I2 SKY data are actually same as those in 202205 run. This is because only N=15 visits were observed in this run (202301). 

NB0391 SKY data are not of very good quality, due to the small number of visits (N=12). This is the first run we use NB0391 filter. In future, we will improve the NB0391 SKY when this bands data are increased.
