TD surprised by large correction needed so soon after the pointing run. Ape error(mount-apes) and madj_ha,dec seems correlated Notes A benchmark 13 data set is taken. Files are name with the data, and instrument in the center. The .apes file is used to produced the graph and data table, focusing the the madj_ha, madj_dec values, which are the IH, ID adjustments to the pointing map to get the star on the crosshairs. commands used: ape_graph.py -f 170324-ishell.ape - to display the output (sh script, data) to the terminal. ape_graph.py -f 170324-ishell.ape | sh - to execute the commands - produces 170324-ishell.ape.png Pointing Bencharmk
