J/ApJS/112/109 Rho Oph Near-IR Positions and Photometry (Barsony+, 1997)
A Near-Infrared Imaging Survey of the Rho Ophiuchi Cloud Core Barsony M., Kenyon S.J., Lada E.A., Teuben P.J. <Astrophys. J. Suppl. Ser. 112, 109 (1997)> =1997ApJS..112..109B
ADC_Keywords: Infrared sources ; Interstellar medium ; Photometry, infrared ; Associations, stellar ; Selected areas ; Positional data Description: This catalog contains the tabulated results from a three-color (JHK) near-Infrared imaging survey of the Rho Ophiuchi star-forming cloud core. The NIR imaging observations were acquired using the SQIID instrument on the Kitt Peak 1.3m telescope from June 4-10, 1993 and April 23-28, 1994. The survey covered one square degree (2.2pc by 2.2pc). The catalog contains 4495 sources with both J2000.0 and B1950.0 coordinates for each source and its J, H, and K magnitudes and/or upper their limits. The Rho Ophiuchi clouds are of great interest for star formation studies, since they include the nearest example of a currently forming star cluster. The absolute positions in RA and Dec were determined for each individual source by using a centering algorithm in the IRAF package APPHOT to obtain center positions in pixels which were then merged into a single common positional grid. Absolute stellar coordinates were determined by comparing the authors positional database with the positions of 36 HST Guide Star Catalog stars spread out over the survey field. These were used to determine a plate scale and rotation which was used to generate the final list of source positions. The position determination technique and the photometric data reduction and calibration is discussed in detail in the source reference. File Summary:

Note on n_Area: (c) The 119 sources SKS detected refer only to sources which are confined to the rho Oph A, rho Oph B, and rho Oph E/F cloud cores, comprising less than half of their entire survey area. (d) WLY conducted an IRAS-selected survey in the K band. They examined 42 fields of 1 square arcmin toward 26 IRAS sources. Note on n_colors: (a) VSSG published J photometry for 11 sources, H photometry for 28 sources, and L photometry for four sources of their list and JHKL photometry of eight sources from the list of GSS. (b) Elias chose 50 sources with H-K > 0.7 for follow-up photometry at bands other than K.
