Data products

Data products, although still in a beta stage, are available via the WWW at

http://ganymede.nmsu.edu/lg

(upon completion of the project, this will be mirrored at at least one other location). The WWW interface provides:

• a summary table of the number of fields found in the HST archive around each galaxy, divided into our three priority categories
• for each galaxy, a DSS finder chart that shows the location of the HST fields, and summary exposure information for each field
• for each field:
  • a DSS finder chart, a single-color mosaic (usually from F555W) of the HST data
  • a link directly into the frames for this field in the HST archive, which shows more detailed information about the exposures and allows users to directly request the raw images
  • a link to the summary photometry output file, as well as the detailed output file produced by HSTPHOT
  • a link to a file with the fake star information
  • links to combined images through each filter. If the field was dithered, there will be a combined image at each sub-pointing
  • a color-magnitude diagram
  • a link to a quality assurance page, which gives graphical display of:
    • aperture corrections
    • difference between small aperture and PSF photometry
    • completeness plots derived from the artificial star experiments
    • summary of information on systematic photometric errors as derived from the artificial star experiments
