- Description:
- High frequency water maser and HI spectra are available through this web service. The water maser phenomena are found in active galactic nuclei (AGN) and have been surveyed with the NRAO Green Bank Telescope. HI spectra are measured mostly from galaxies in the local Universe.

- Description:
- This table records high-level information for the observations obtained with Hitomi and provides access to the data archive. The Hitomi mission was launched on a JAXA H-IIA into low Earth orbit on February 17, 2016, at 5:45 pm JPS from Tanegashima Space Center. Hitomi was equipped with four different instruments that together cover a wide energy range 0.3-600 keV. The Soft X-ray Spectrometer (SXS), which combined a lightweight Soft X-ray Telescope paired with a X-ray Calorimeter Spectrometer, provided non-dispersive 7-eV resolution in the 0.3-10 keV bandpass with a field of view of about 3 arcminutes. The Soft X-ray Imager (SXI) expanded the field of view with a new generation CCD camera in the energy range of 0.5-12 keV at the focus of the second lightweights Soft X-ray Telescope; the Hard X-ray Imager (HXI, two units) performed sensitive imaging spectroscopy in the 5-80 keV band; the non-imaging Soft Gamma-ray Detector (SGD, two units) extended Hitomi's energy band to 600 keV. On March 27, 2016, JAXA lost contact with the satellite and, on April 28, announced the cessation of the efforts to restore mission operations. At that time Hitomi was in check-out phase and had started the calibration observations. Data were collected from six celestial objects (Perseus, N132D, IGR_J16318-4848, RXJ1856.5-3754, G21.5-0.9, and Crab) as well as black sky for a total of about one month of data. The data from these observations were divided into intervals of one day if the observation of a specific pointing was longer that one day. A sequence number was assigned to each observing day and within data from all instruments are included. The day division was mainly to limit the data size within a sequence number. There are in total 42 sequences, and each record in this database table is dedicated to a single sequence. The early observations do not contain data from all instruments and in cases the object was not always placed at the aim point. This database contains parameters to indicate which instrument was on and if the celestial source was in the field of view. The SXS was the first instrument to turn on and therefore all observations contain SXS data, although the thermal equilibrium was reached after March 4 2016. The second instrument was the SXI followed by the HXIs and, finally, the two SGDs. This database table was generated at the Hitomi Science Data Center processing site (Angelini, L., Terada, Y, et al., 2016, SPIE 9905E, 14) with additions to indicate which instrument was on and if the source was in the FOV. It was ingested into the HEASARC database in June 2017. This is a service provided by NASA HEASARC .

- Space Telescope Science Institute Archive
- Description:
- The Hopkins Ultraviolet Telescope (HUT) was one of three ultraviolet instruments of the ASTRO-1 mission flown on the space shuttle Columbia during 2-10 December 1990. 106 spectrophotometric observations of 77 targets were obtained in the far-UV (i.e., 912-1850 Ã…) at a resolution of ~3 Ã…. A few sources were observed in the 415-912 Ã… region with a 1.5 Ã… resolution. The same three instruments were later flown on the space shuttle Endeavour from 3-17 March 1995 as part of the ASTRO-2 mission. During the longer ASTRO-2 mission, 385 observations of 265 targets were obtained.

- Description:
- MAST-produced spectral container files for STIS spectra. STIS spectra range from 1150 to 10,300 at low to medium spectral resolution, high spatial resolution echelle spectroscopy in the ultraviolet. STIS began operation in 1997. (Note the included echelle spectra are technically not yet supported by the SSAP.)

- Publisher:
- CRAL-Observatoire de Lyon
- Description:
- A compilation of 1D reference spectra of stars and galaxies. Spectra from several archives and libraries have been collected, re-documented and re-formatted. The spectral resolution is between R=100 and 250000. Some spectra give the physical flux, either or not corrected for the Galactic extinction, and some others are normalized to the pseudo-continuum. Some are given in physical units, and some are momalized to some particular wavelengths (often 5500 A).
