LAMOST DR1 totally releases 2,204,860 spectra, include 717,660 objects of the pilot survey (2011-10-24~2012-06-30), and 1,487,200 objects of the regular survey (2012-09-28~2013-06-30). DR1 includes two types of data: optical spectra (flux- and wavelength-calibrated, sky-subtracted), and catalog data, which includes both parameters measure from spectra, such as redshifts and signal to noise ratios, and parameters inherited from input catalogs. You should keep in mind that LAMOST is a spectral survey telescope, and the parameters related to photometry, which you get here, all come from other surveys.
With time, all HEAVENS products should become available on the Virtual Observatory.
In some cases this requires an enhancement of the Virtual Observatory standards.
For now the following HEAVENS services are available through the VO:
- SIAP Image cutout service for INTEGRAL/ISGRI and JEM-X
- Timeseries service for INTEGRAL/ISGRI, JEM-X and OMC
Wished features include:
- Extended Query Parameters for time intervals
- Extended Query Parameters for energy bands
- Timeseries service for INTEGRAL/IREM and SPI-ACS
- Spectra service for all INTEGRAL instruments
These spectra are optical follow-up observations of the
X-ray sources detected in the 942 ks exposure of the
Chandra Deep Field-South (CDFS) using FORS.
EXES operated in the 4.5 - 28.3 um wavelength region, at high (R ~ 50,000 - 100,000), medium (R ~ 5000 - 20,000) and low (R . 1000 - 3000) spectral resolution.
FIFI-LS was an integral field, far-infrared spectrometer. The instrument included two independent grating spectrometers sharing a common field of view (FOV). The short wavelength spectrometer (blue channel) operated in the 51 - 120 um wavelength region, and the long wavelength spectrometer (red channel) covered 115 - 200 um. The spectral resolution ranged from 600 to 2,000 dependent on the observed wavelength, with higher values towards the long wavelength ends of each spectrometer.
FLITECAM was an infrared camera operating in the 1.0 - 5.5 um waveband. It consisted of a 1024x1024 InSb detector with 0.475"x0.475" pixels and used refractive optics to provide an 8' diameter field of view. The instrument had a set of filters for imaging, and grisms for moderate resolution spectroscopy. The filter suite consisted of standard Barr filters used for imaging at J, H, K, L and M in one filter wheel. A second filter wheel held a selection of narrow-band imaging filters including Pa-alpha, Pa-alpha continuum, 3.07 um H2O ice, 3.3 um PAH, L-narrow and M-narrow. Additionally there were order sorting filters for use with the grisms. A selection of three grisms was available to provide medium resolution (R ~ 1500) spectra over the entire wavelength range.
FORCAST was a dual-channel mid-infrared camera and spectrograph sensitive from 5 - 40 um. Spectroscopy was also possible using a suite of grisms, which provided coverage from 5 - 40 um with a low spectral resolution of R ~ 200.
The German REceiver for Astronomy at Terahertz Frequencies (GREAT) was a modular heterodyne instrument with multiple configurations that provided high-resolution spectra (up to R = 1e8) in several frequency windows between 0.4900-4.7448 THz.
