Starter star lists

The sets of 'starter stars' that I used are listed below, I use the term 'provisional' to describe ra coordinates that still have an unknown zero point. At this point in the reductions, I had no absolute reference for my ra values. They were still provisional.

I took the first star in each set and assigned it a provisional ra of zero. I then created two columns of provisional ras, one constructed by sequentially adding the modern delta ras, and the second by adding my measured delta ras. The first of these two columns is labelled Ycat_prov_ra, and the second column meas_prov_ra. The first of these two columns will always sum to 360 degrees. The second column will come close, but contains my measurement errors.

The headers are:

c0 starname1

c1 Ycat_ra1, YBSC ra1 , also known as 'the modern value' (YBSC = the Yale Bright Star Catalog )

c2 Ycat_dec1, YBSC dec1

c3 starname2

c4 Ycat_ra2

c5 Ycat_dec2

c6 my measured delta ra

c7 number of linkages to other primary stars

c8 number of measured separations for this pair of stars

c9 Ycat_dra, the modern delta ra (c4 - c1)

c10 my delta ra measurement error (c6 - c9)

c11 Ycat_prov_ra, the running sum of c9 (always ends with 360.0)

c12 meas_prov_ra, the running sum of c10, from my measurements

c13 my accumulating ra error as compared to the modern value (c12 - c11)
