Beginning of ReadMe : J/ApJ/672/266 ARAUCARIA project: NGC 55 Cepheids JK magnitudes (Gieren+, 2008) ================================================================================ The Araucaria project: near-infrared photometry of Cepheid variables in the Sculptor galaxy NGC 55. Gieren W., Pietrzynski G., Soszynski I., Bresolin F., Kudritzki R.-P., Storm J., Minniti D. <Astrophys. J., 672, 266-273 (2008)> =2008ApJ...672..266G ================================================================================ ADC_Keywords: Stars, variable ; Photometry, infrared Keywords: Cepheids - distance scale - galaxies: distances and redshifts - galaxies: individual (NGC 55) Abstract: We have obtained deep images in the near-infrared J and K filters of four fields in the Sculptor group spiral galaxy NGC 55 with the ESO VLT and ISAAC camera. For 40 long-period Cepheid variables in these fields, which were recently discovered by Pietrzyski et al., we have determined mean J and K magnitudes from observations at two epochs, and derived distance moduli from the observed period-luminosity (PL) relations in these bands. Description: We used deep J- and K-band images recorded with the 8.2m ESO VLT equipped with the Infrared Spectrometer and Array Camera (ISAAC). Four 2.5'x2.5' fields were observed in service mode on seven nights between 2004 July 18 and September 21.
