Position Angle

Start of an observing week at the WHT on La Palma. Spent the day talking to the friendly ING staff on the Snowhite project (do all dwarfs have dusty beards?) and the scheduling and configuration of the service observations they will be doing later in the semester for another SoeperSecret project.

Meanwhile, I still need to determine the positon angle of the slit for the observations that are going to start tomorrow night. Slow but steady progress. With some finagling these long-slit observations of occulting pairs of galaxies can hold quite a bit of information in one go. Thanks to the GalaxyZoo, we are certainly not lacking in targets!
