19 PDS DSV 1 This table contains diffraction-all K-alpha diffraction data for the Rock Hall drill sample, analyzed in CheMin cell number 7b (Mylar window). The table represents results from sequences uploaded on sol 2264, including the 4 initial minor frames that represent 2 hours of analysis. Although a total of 15 minor frames were collected in this first night of analysis, a drop in sample signal beyond the first four minor frames indicated that much of the sample had moved to portions of the cell outside the X-ray beam; when sample signal rose again toward the end of this analysis, grain motion deteriorated significantly. Additional nights of analysis on sols 2277-2278 and 2285-2286 showed no improvement in grain motion, even as attempts were made to increase sample vibration intensity. An RDA for this later analyses has been generated as CMA_599656708RDA22770731206CH00113P1, but that RDA has not been used to prepare a MIN file because of the very poor grain motion in these subsequent nights of analysis. To focus on the highest quality data, the RDA file listed here and used for mineralogical analysis (see file CMA_598547494MIN22650731206CH00111P1) contains only the first four minor frames where signal remained strong and grain motion was good. Refined plagioclase c and gamma cell parameters were used to make a minor adjustment in the sample to detector distance, reducing this by 69 um. CCD temperatures during data collection were ~-50 degrees centigrade. Column 1 of the table lists 2-theta from 2.00 to 52.00 degrees cobalt K-alpha, in increments of 0.05 degrees (1001 entries). Column 2 lists the intensity of the diffraction for each 2-theta value in column 1. 1001 Carriage-Return Line-Feed Comma 2 0 2-THETA 1 ASCII_Real 6 degrees 2-theta INTENSITY 2 ASCII_Real 7 count The intensity of the diffraction for each 2-theta value in column 1 cma_598547494rda22650731206ch00111p1.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
