A Survey with the HST

Poster 53.09 presented at the 185th meeting of the American Astronomical Society, Tucson, January 8-12, 1995.

Abstract

The Hubble Space Telescope has been used to observe a strip of 28 overlapping WFPC-2 fields. All fields but one are observed for a total of 2800 seconds with F606W (V) and 4400 seconds with F814W (I). The estimated limiting magnitude is ~27.5 to 28. One field (the "deep" field) has a total exposure of 24400 seconds in V and 25200 seconds in I.

In this poster, we present the data and a progress report. The science to be done with these data includes study of the number magnitude relation, angular size distributions, morphology, and clustering. All of these are affected by the cosmological model and scenarios for galaxy and cluster formation which are the scientific questions we will eventually address.


The following postscript files were presented in the poster:

Files i0409.ps, i1015.ps, i1621.ps, i2227.ps, and i2831.ps can be printed, cut, and pasted together to show the survey in the I band. Files v0409.ps, v1015.ps, v1621.ps, v2227.ps, and v2831.ps are the same for the V band. These files really have to be printed to see much; ghostscript rendering leaves a lot to be desired!

Authors.ps lists the authors (surprise!). Description.ps is a description of the survey and deep.ps is a description of the deep field. Survey_strip.ps shows how the fields lie on the sky. Sample_v_distribution.ps and sample_v_minus_i_dist.ps show preliminary data for chip 2 of the deep field.

All of the above are exactly what was presented in the poster. In addition, we had color prints of the deep field. C7.gif is a color rendering of chip 2 of the deep field with V used for blue, I used for red, and their average for green (with some enhancement of the saturation to make it look better!).

As a bonus, c17.gif is a color rendering of a mosaic of all four chips of field 17. This is a 1487 x 1508 image (0.1 arcsecond pixels). C17s.gif is a 1280 x 1024 subimage which makes a nice root window background for your workstation.
