ADC_Keywords: Clusters, open ; Stars, pre-main sequence ; Photometry, UBVRI ; Photometry, H-alpha ; Photometry, infrared Keywords: stars: formation - stars: pre-main sequence - ISM: HII regions - ISM: dust, extinction - ISM: individual objects: IRAS 07141-0920 - ISM: individual objects: Sh2-294 (S294) Abstract: High-resolution optical UBVRI and Hα images obtained with ALFOSC mounted on the Nordic Optical Telescope (NOT), near-infrared JHKS images obtained with NOTCam at the Nordic Optical Telescope, and VLT/ISAAC images obtained through the H2 (2.12µm) filter were all used to make photometric and morphological studies of the point sources and the nebula seen towards Sh2-294. Identification of PMS members was done using three different methods: comparison with isochrones in optical colour-magnitude diagrams and detection of either near-IR excess or Hα emission. Description: We report the properties of a new young double stellar cluster in the region towards IRAS 07141-0920 contained in the HII region Sh2-294. High-resolution optical UBVRI and Halpha images, near-infrared JHKs and H2 filter images were used to make photometric and morphological studies of the point sources and the nebula seen towards Sh2-294. This Table contains the optical and near-IR photometry of the point sources found in this region, detected in at least one of our U, B, V, R, I, and Hα images. File Summary:

Note (1): A 99.99 entry indicates a non-detection. Note (2): Membership assignment as follows: 1 = MS member 2 = membership assignment in 2 CM diagrams, V vs B-V, V-R, and V-I 3 = membership assignment in 3 CM diagrams, V vs U-B, B-V, V-R, and V-I Note (3): NIR excess as follows: 0 = no IR excess from J-H/H-Ks diagram 1 = probable IR excess source 2 = bona-fide IR excess source
