Robin,

The spectrum is in the same Y position on the sensor for all observations.

Peter, My Lhires suffers from the same problem, you are not alone. So, I use SPOX, and do not touch the Lhires at all. Sometimes I see a wavelength calibration shift, sometimes I don't. It seems works to some degree. For us, everything in Spectroscopy is a compromise, do you want to get acceptable s...

Further to my previous question, I would like to ask the following in order to better understand the bigger picture; 1. What is the ultimate purpose of this study ? Is it to accurately determine the V/R period of Pi Aqr or is it for another purpose ? 2. The V/R period was 84 days, then it was 42 day...

Here is my effort.

Any comments ?
