JHK imaging of HII regions. The fields contain quite bright stars: a waiver was submitted and approved for this reason. Excellent seeing is a strong requirement for the scientific goals of the project. Generic offset template used due to the crowdedness of the field and the associated nebulosity; user chose the grid positions to ensure an acceptable sky subtraction. Short DITs used due to the need to sample a large dynamic range including bright stars. One OB for each filter and field must be done under photometric conditions, the other can be done in clear conditions. Calibration plan is enough, no time-critical aspects.
