This program verifies that FUV spectroscopic target acquisitions are working nominally for the modes allowed in cycle 29doublePoint G130M at LP5 comma G140L at LP4 comma and G160M at LP4. For each grating the cenwave with the widest cross dispersion profile in which acquisitions are done is used comma yielding the combinations G130M-1291 comma G140L-1280 comma and G160M-1600. After the standard target WD 1657+343 is centered using ACQ-IMAGE we take spectra at the NUM-POS positions used by the PEAKXD and PEAKD algorithms to inspect those regions of the detector and check the vignetted flux. We then perform a PEAKXD and-or PEAKD acquisition and take a spectrum to verify centering. We test PEAKXD with NUM-POS=3 (default) and 5 comma and PEAKD with NUM-POS=5 (default). A detailed description of the observations is given in the visit level comments. This program follows the prescription used in the last several cycles comma and is most recently adapted from cycle 28 program 16326.
