VizieR Online Data Catalog: Cores in California molecular cloud (Zhang+, 2018)

The Herschel data include PACS 70 and 160um (Poglitsch et al., 2010A&A...518L...2P) and SPIRE 250, 350, and 500um (Griffin et al., 2010A&A...518L...3G) imaging for the CMC (Harvey et al., 2013ApJ...764..133H, Cat. J/ApJ/764/133). We used the Harvey et al. (2013ApJ...764..133H, Cat. J/ApJ/764/133) version instead of the current HSA pipeline products, see Harvey et al. (2013ApJ...764..133H, Cat. J/ApJ/764/133). We made a high-resolution (18.2") H₂ column density map with with Herschel four-band emission from 160 to 500um. Using this map, we extracted a complete core sample with the fellwalker algorithm. Single-pointing observations at 30 positions near 90GHz were carried out in April 2014 using the IRAM 30m telescope on Pico Veleta, Spain. The frequency coverage includes the ground rotational (1-0) transition of H¹³CO⁺, HN¹³C, C₂H, HCN, HCO⁺, HNC, N₂H, C¹⁸O, and ¹³CO. The single-pixel heterodyne receiver of the Eight MIxer Receiver (EMIR) with a band-width of 16GHz in two orthogonal polarizations was employed to simultaneously observe these nine lines. The fast Fourier transform spectrometer (FTS)backends were set to 200kHz (about 0.65km/s at 90GHz) resolution.
