Preview data
Preview images (pmg format) of the drizzled combined images in the three filters F220W, F555W and F892N are available here. The fits images can be downloaded by ftp from the Download page.
The slitless spectra are presented in a form suitable for browsing. For each object for which a spectrum was extracted (with the direct object taken directly from the F555W image or from the GOODS CDFS catalogue), one entry presents the salient features of the target and the extracted spectrum. The columns are:
- Obect number - a running number from 1 for the objects catalogued from the HRC F555W image; from 101 for the objects found in the GOODS CDFS catalogue;
- Magnitude - F555W magnitude for the objects catalogued from the HRC F555W image; F850LP (z band) magnitude for the objects from the GOODS CDFS catalogue;
- Image-coordinates - the position of the object on the HRC drizzled direct images and the corresponding RA and Dec (J2000);
- Direct image - an image cut-out of the direct image from the HRC F555W image;
- Grism stamp - a cut-out of the 2D 1st order spectrum of the object;
- Raw spectrum - the extracted 1D spectrum in counts v. wavelength (A) with error bars;
- Calibrated spectrum - the extracted 1D spectrum in flux (ergs/cm/cm/s/A) v. wavelength with error bars. Points in blue have been flagged as possibly contaminated by a nearby spectrum.
More details of the extraction process and combination of the spectra from each singe image can be found here.
The spectra of each individual object, as FITS binary tables or as ASCII files, can be downloaded by ftp from the Download page.
