I am a professional astronomer at Marshall Space Flight Center working in the Meteoroid Environment Office (MEO), having started this job just a few weeks ago. One of my first jobs has been to put together a new analysis pipeline for our observations of comets, and I think I have managed to put together an almost entirely automated end-to-end pipeline that automatically does photometric calibration. However, I now need to do some diagnostic tests on how well my photometric calibration works. The MEO has been getting observations of two Henden start fields every night we get comet data, so I would like to use those to determine the accuracy and precision of my photometry. However, I cannot seem to find good catalog of the Henden star fields/objects online thus far. I know of the old ftp site that used to have them but I gather that is out of date now.
So my question is: Is there any place on AAVSO or elsewhere where I can download the entire catalog of Henden star fields, ideally in a FITS format? I would like the entire survey catalog if possible, as I will be using a large number of Henden fields over the course of the year to maintain the photometric accuracy of my own pipeline. Specifically, I am doing observations in R, B, V, and I band of the comet that I need to calibrate
