Source HSC data, upon which our LSB simulated images are based.
- calexp : HSC SSC DR1 calexp image files (stripped of mask and weight HDUs)
- files are in the format 'calexp-FACILITY-BAND-TRACT-PATCH.image.fits'
- originally 57 files, trimmed to two (minimum and maximum density patches)
- additional raw data added after trimming to final two:
- GRIZY coverage
- segmentation check image
- segmentation check PNG
- magellip : plot of apparent magnitude as a function of half-light radii and ellipticity
- used to calibrate ellipticities
- magradii : plot of apparent magnitude as a function of half-light radius
- used to extrapolate half-light radii to the brightest (and faintest) regimes
- numcounts : plots of galaxy number counts as a function of magnitude
- patchden : analysis of field densities for original 57 HSC SSC DR1 patches
- psf : PSF generation, and associated analysis figure
- sourcecats : generation of source catalogues for 57 unique tract/patch r-band HSC SSC DR1 images
- one catalogue and one analysis check image (segmentation map) for each of the original 57 patches
- additionally contains defaults SExtractor config files
- threshold level histogram and ancilliary data
- stamps : postage stamp images
A complete manifest of all HSC SSC DR1 files, including WCS information, header data and basic aperture flux tests. File in R RDS data format. See Kelvin et al. 2019 for further information.
