Beginning of ReadMe : J/ApJS/209/28 MYStIX Wide-Field NIR data: crowded fields (King+, 2013) ================================================================================ The MYStIX wide-field near-infrared data: optimal photometry in crowded fields. King R.R., Naylor T., Broos P.S., Getman K.V., Feigelson E.D. <Astrophys. J. Suppl. Ser., 209, 28 (2013)> =2013ApJS..209...28K ================================================================================ ADC_Keywords: Photometry, infrared ; H II regions Keywords: infrared: stars - methods: data analysis - open clusters and associations: general - stars: formation - stars: pre-main sequence - techniques: photometric Abstract: We present JHK infrared data from the UK InfraRed Telescope (UKIRT) for a subset of the regions of the Massive Young Star-Forming Complex Study in Infrared and X-ray (MYStIX) survey. Some of the data were obtained specifically for the MYStIX project, and some as part of the UKIRT Infrared Deep Sky Survey's Galactic Plane Survey (UKIDSS). In most of these fields, crowding is a significant issue for aperture photometry, and so we have re-extracted the photometry from the processed images using an optimal extraction technique, and we describe how we adapt the optimal technique to mitigate the effects of crowding. Description: The data were obtained using WFCAM, the IR wide-field camera on UKIRT in Hawaii for 11 regions (DR 21, Eagle Nebula, Lagoon Nebula, M 17, NGC 1893, NGC 2264, NGC 2362, NGC 6334, NGC 6357, Rosette Nebula and the Trifid Nebula). Roughly half the fields were observed as part of the Galactic Plane Survey (GPS; Lucas et al. 2008, Cat. II/316) component of UKIDSS with the remainder being obtained in Director's Discretionary Time (DDT) using identical observing procedures.
