- Description:
- Smooth X-ray morphology and non-detection of a radio source at the center of A2589 indicate that it is a typical case of a well-relaxed regular galaxy cluster. In this paper, we present a multicolor photometry for A2589 (z=0.0414) with 15 intermediate bands in the Beijing-Arizona-Taiwan-Connecticut (BATC) system which covers an optical wavelength range from 3000{AA} to 10000{AA}. The spectral energy distributions (SEDs) for more than 5000 sources are achieved down to V~20mag in about a 1{deg}^2^ field. A2589 has also been covered by the Sloan Digital Sky Survey (SDSS) in photometric mode only. A cross-identification of the BATC-detected galaxies with the SDSS photometric catalog yields 1199 galaxies brighter than i=19.5mag, among which 68 member galaxies with known spectroscopic redshifts are found. After combining the SDSS five-band photometric data and the BATC SEDs, photometric redshift is applied to these galaxies to select faint member galaxies. The color-magnitude relation is taken as a further restriction of early-type cluster galaxies. As a result, 106 galaxies are newly selected as member galaxies.

- Description:
- Multi-color photometry data of the project, "Large Field Multi-Color Sky Survey" supported by Beijing-Arizona-Taiwan-Connecticut (BATC) is presented. From 1995 to 2004, 110 58'x58' sky survey fields have been observed. First release of BATC catalog includes observation results for 511842 sources located in 70 sky survey fields. The whole release is divided into 70 files. Each file corresponds to one observation field. The BATC filter system includes 15 intermediate band filters, covering a range in optical wavelengths from 300 to 1000 nm. The telescope used is a 60/90 cm f/3 Schmidt telescope located at Xinglong Station of National Astronomical Observatories. A Ford Aerospace 2048x2048 CCD camera with 15 micron pixel size is mounted at the Schmidt focus of the telescope. The field of view of the CCD is 58'x58' with a plate scale of 1.7arcsec per pixel. The BATC magnitude system adopts the AB magnitude system, defining as M_batc_ = -2.5log(F_{nu}_) - 48.60 where F_{nu}_ is the flux per unit frequency in units of erg/s/cm^2^/Hz, and F_{nu}_={Sum}[d(log{nu})*f_{nu}_*R_{nu}_]/{Sum}[d(log{nu})*R_{nu}_] where R_{nu}_ represents the response of the system. Four Oke & Gunn (1983ApJ...266..713O) standards, HD 19445, HD 84937, BD+26 2606 and BD+17 4708 are observed in photometric nights for flux calibration. We provide catalogues down to i-band (666nm) about 20 mag with complete spectral energy distributions (SEDs) for each object. Typical error in photometry is about 0.02-0.05 mag. There is usually the deepest observation at i-band. Most of the catalogs use i-band data as their reference for coordinate calibration. While, "T0329","TA01" and "TA03" use j-band as reference. All colors in the "TA04" catalog have no photo calibration. For detailed information of the data reduction, please refer to: Zhou, X., Jiang, Z., Ma, J., et al. 2003, 2003A&A...397..361Z

- Description:
- We present photometric data of the Type II-P supernova (SN) 2004dj in NGC 2403. The multicolor light curves cover the SN from 60 to 200 days after explosion and are measured with a set of intermediate-band filters that have the advantage of tracing the strength variations of some spectral features.
