| addwave |
addwave is software to
reconstruct and append a classic WAVE HDU (reconstructed from
the FLUX HDU WCS information) to a file that has been downloaded
from the archive. We provide a C version (with a few bells and wistles)
and a bare-bones IDL version. |
| cspec |
cspec is used to view 1-D data in the
form y=f(x), specifically spectra. It can open text files with
columnar data separated by white space or binary files in a format we
refer to as 'unifspec', which is a format devised by Kris Davidson
for his own scientific purposes. cpsec internally oversamples the
data with an interpolation routine to ease the process of
integrations for equivalent width and integrated flux calculations.
Thus, the plots displayed in cspec are a representation of the data
as a function, not the original data points. In theory this
data is as least as good if not better than the original data. |
| exfits |
exfits is a tool for performing simple row- and column-based extractions on 2D HST STIS spectra. |
| fitstools |
fitstools is another library for
handling FITS data. It wraps CFITSIO and adds functionality for other
FITS file operations. |
| ghostbgone |
ghostbgone is software to remove the H-alpha ghost image from the STIS/CCD exposures in the H-alpha wavelength range. |
| libuni |
libuni is a C library for handling
interpolated, over-sampled data in some of the other software
packages on this page. It is a prerequisite for cpsec among other
things. |
| replacenan |
replacenan is software which replaces NaN (not-a-number = -999./0.) in the FLUX arrays of the FITS files with any other number that the user specifies. |
cfitsio |
Most of these software products make use of the CFITSIO subroutines developed at NASA/GSFC. |
