Flat-fielding of ACS WFC grism data
N. Pirzkal, A. Pasquali, J. Walsh
In direct imaging, broad band flat-fields can easily be applied to correct deviation from uniform sensitivity across the detector field. However for slitless spectroscopy data the…

The Wavelength Calibration of the WFC grism
A. Pasquali, N. Pirzkal, J. R. Walsh
We present the wavelength solution derived for the G800L grism with the Wide Field Channel from the spectra of two Galactic Wolf-Rayet stars, WR 45 and WR 96. The data were acquire…
