2025 June 13: The HLA cart and HLA footprint viewer no longer work. Minimal
maintenance is being done on the HLA interface because all HLA
functionality and data products will soon be available in the new MAST
Hubble search interface.
At that point,
the HLA interface will
be retired. Note that the HLA products will still be available.
Click on data links to immediately download data.
If you need footprints, we recommend using the
MAST Portal.
Note that both the Portal and the new search interface also provide access to the
Hubble Advanced Products (HAP), which include HLA-style products for more recent
observations.
The HLA contains no observations acquired after 2017 October 1.
Also known as NGC 4459, VCC1154 is an S0 galaxy with a spectacular dust lane in the Virgo Cluster.
Highlighted HLA Feature - Use of Lighter/Darker buttons in the Interactive Display to explore the full dynamic range of an image.
This display can be reproduced in the HLA by clicking on the image
above (then clicking the "Darker" button several items), or by following these steps:
- Typing hla.stsci.edu into your browser.
- Click on the "Enter Site here" button.
- Type "VCC1154" into the empty search box. Hit the "return/enter" key or click on the "Search" button.
HLA does a name resolution of your target and displays the
RA/DEC and radius of your target. HLA will then search its database for images that meet your RA/DEC and search radius.
The results will be displayed in a tabular format.
- Click on the "Images" tab. HLA will display a preview of the available images.
- Scroll down to the VCC1154 (color) 9401_13 image. This is a combined image from two exposures using the F850LP and F475W filters.
- Click on the Interactive display link under the preview of the color image. HLA will open a new window with your image using the HLA's
interactive display capability.
- Use your mouse button to grab & drag the image such that the galaxy is at the center of the display.
- Now zoom in by clicking the "+" control at the upper left of the display.
- Click seven times on the "Darker" button to get to this specific contrast level.
From the HLA one can look at footprints of HST observations on the sky, download
images, display source lists, filter/sort your search results, make your own
version of the color images with the "advanced contrast controls",
... etc. explore !
