Illustrate that STIS has the capability of acheiving S/N of 100:1 in both Band 1 {115-170 nm} and Band 2 {165 - 310 nm}. This demonstration is especially important in Band 1 where the MAMA1 window is inclined and the dependance of the flat on angle of incidence on the detector voided some of the ground based data. These observations will be conducted by observing the target {BD28D4211} in the FP split slits. This will constrain motion of the target to be purely in the spectral direction. Non-integral steps will be used. By illuminating different pixels in the spectral direction, but not the spatial direction, enabling an iterative algorithm to solve for and remove the fixed pattern noise. The array will be read every 6 minutes to preserve the spectral identity of the illuminated pixels in the presence of doppler compensation. One 10 minute observation will also be taken with each slit. Thus we will have a means of acheiving high signal-to-noise data independant of a high-signal-to noise ground based flat in Band 1 or a post-launch flat for either band. In addition, this proposal will check the FP-split slit methodology. Note: this method will require a minimum signal-to-noise of 140:1 to acheive a signal-to-noise of 100:1, given that a in-flight flat field will not be available at this time.
