- Description:
- The Bochum Galactic Disk Survey is an ongoing project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been recorded since mid-2010 in Sloan r and i simultaneously with the RoBoTT Telecsope at the Universitaetssternwarte Bochum near Cerro Armazones in the Chilean Atacama desert. It contains measurements of about 2x10^7 stars over more than seven years. Additionally, intermittent measurements in Johnson UVB and Sloan z have been recorded as well.

- Publisher:
- The GAVO DC team
- Description:
- This is a deep optical mosaic of the Fornax cluster’s core, covering 1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI, using a transparent filter that nearly equals the no-filter throughput and thus provides a high signal-to-noise ratio. Based on an approximate conversion to V-band magnitudes, the unbinned and binned mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and 27.8 mag/sq.arcsec, respectively.

- Description:
- In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at approximately 12h45m +44°30′ and 1h00m +28°00′ and spanning 4178 and 1457 square degrees respectively. The images were derived from 3,451 hrs (7.6 PB) of LOFAR High Band Antenna data which were corrected for the direction-independent instrumental properties as well as direction-dependent ionospheric distortions during extensive, but fully automated, data processing. A catalogue of 4,395,448 radio sources is derived from our total intensity (Stokes I) maps, where the majority of these have never been detected at radio wavelengths before. At 6′′ resolution, our full bandwidth Stokes I continuum maps with a central frequency of 144 MHz have: a median rms sensitivity of 83 μ Jy/beam; a flux density scale accuracy of approximately 10%; an astrometric accuracy of 0.2′′; and we estimate the point-source completeness to be 90% at a peak brightness of 0.8 mJy/beam. By creating three 16 MHz bandwidth images across the band we are able to measure the in-band spectral index of many sources, albeit the error on the derived spectral index is > ±0.2 which is a consequence of our flux-density scale accuracy and small fractional bandwidth. Our circular polarisation (Stokes V) 20′′ resolution 120-168 MHz continuum images have a median rms sensitivity of 95 μ Jy/beam, and we estimate a Stokes I to Stokes V leakage of 0.056%. Our linear polarisation (Stokes Q and Stokes U) image cubes consist of 480 97.6 kHz wide planes and have a median rms sensitivity per plane of 10.8mJy/beam at 4′ and 2.2mJy/beam at 20′′; we estimate the Stokes I to Stokes Q/U leakage to be approximately 0.2%. Here we characterise and publicly release our Stokes I, Q, U and V images in addition to the calibrated uv-data to facilitate the thorough scientific exploitation of this unique dataset. This service queries the Stokes I continuum mosaic images.

- Description:
- These FITS images were generated with the IDL package MIRphot [Asmus2014]_ by extraction (and combination) of the sub-images from the chopped/nodded total images from COMICS, Michelle, T-ReCS and VISIR (see [Asmus2014]_ for details). The FITS images contain the central ~4 arcsec of each source centered on the (putative) nuclear position with North being up and East to the left. The WCS registration has been performed after extraction by using coordinates of the nucleus from other wavelengths (mostly 2MASS and NED). The uncertainty of these reference position is usually less than 1 arcsec. In addition, the imprecision of the assignment itself is ~1px ~ 0.1". The FITS images are flux calibrated (unit is mJy) using the Gaussian 2D fits to the corresponding STD observation (where available, otherwise using the median conversion factor for the used instrument/filter settings). Therefore, correction factors have to be applied in case other flux measurement methods are applied to the images. The flux values given in the FITS headers should be regarded as approximate values. In particular for the instruments, VISIR and COMICS, they are not necessarily exactly equal to the values provided in the photometry results table, because many flux measurements were performed during the process of combining individual subimages (all in MIRphot), instead of in the final combined image, provided here. The used total images are available upon request. Note, however, that these are just the products of the observatory-delivered pipelines with default parameters. ..

- Description:
- These are 1.4GHz Very Long Baseline Interferometry images of 532 radio sources with a flux density exceeding 100uJy as determined by Ibar et al. (2009, MNRAS, 397, 281), obtained between 2010-06-03 and 2010-09-03. For all fields, we give frames processed using natural weighting to preserve maximal sensitivity. For the 65 detected sources, we additionally give frames processed using uniform weighting to suppress sidelobes (see Middelberg et al. 2013, A&A 551, 97 for details) in flux density measurements. Some sources have larger images to cover a larger area because the initial coordinates were not sufficiently accurate.
