J/ApJS/155/123 JHKs photometry of ultracompact HII regions (Alvarez+, 2004) ================================================================================ Near-infrared subarcsecond observations of ultracompact H II regions. Alvarez C., Feldt M., Henning T., Puga E., Brandner W., Stecklum B. =2004ApJS..155..123A ================================================================================ ADC_Keywords: H II regions ; Photometry, infrared Keywords: catalogs - H II regions - infrared: ISM - instrumentation: adaptive optics - techniques: high angular resolution Abstract: We present adaptive optics (AO) assisted J, H, and K/K' images of eight ultracompact HII (UC HII) regions taken with the ALFA (Adaptive optics with a Laser For Astronomy) and ADONIS (ADaptive Optics Near-Infrared System) AO systems at Calar Alto and La Silla observatories. The images show details of the stellar population and the near-IR morphology of UC HII regions with unprecedented resolution. Description: The observations using the AO system ALFA on the 3.5m telescope at the German-Spanish astronomical center on Calar Alto (Spain), were part of the ALFA science verification program. This program was carried out from fall 1999 to fall 2000. The ADONIS observations were carried out in 2000 March.

Both components are included in the field of our near-IR images. Component A classified as spherical, and component B as irregular. Note (2): Right ascension and declination of the peak radio emission taken from the literature (Equinox J2000). Note (3): Radio morphological type from Wood & Churchwell (1989ApJS...69..831W), Walsh et al. (1997, Cat. ), and Kurtz et al. (1994, Cat. ), depending on the source. The codes used have the following meaning: UN = Unresolved/spherical, CO = cometary, CH = core-halo, SH = shell, IR = irregular/multipeaked. -------------------------------------------------------------------------------- Byte-by-byte Description of file: refs.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 2 I2 --- Ref Reference number 4- 22 A19 --- Bibcode Bibcode 24- 40 A17 --- Aut Author's name 42- 63 A22 --- Com Comments -------------------------------------------------------------------------------- Byte-by-byte Description of file: table3.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 12 A12 --- Name Object name (as in table1) 14- 16 I3 --- Seq Source number in Name ([AFH2004] in Simbad) 18- 19 I2 h RAh Hour of Right Ascension (J2000) 21- 22 I2 min RAm Minute of Right Ascension (J2000) 24- 28 F5.2 s RAs Second of Right Ascension (J2000) 31 A1 --- DE- Sign of the Declination (J2000) 32- 33 I2 deg DEd Degree of Declination (J2000) 35- 36 I2 arcmin DEm Arcminute of Declination (J2000) 38- 41 F4.1 arcsec DEs Arcsecond of Declination (J2000) 44- 48 F5.2 mag Jmag ?
