Astronomical Catalogs

Accurate Globular Cluster List - A list of globular clusters with observables data, checked for accuracy, available as a fixed record length text file or as a SkyMap Pro native catalog.

Tycho Double Star Catalog for SkyMap Pro. This zip file (1.6 megs) contains a fixed record length text file, and a SkyMap SDD file describing its format. You can use the SDD file in SkyMap's Data Catalog Preparation Tool to compile the text file into a fast SDC file.

The TDSC was altered in the following ways:

• Positions were precessed to J2000.0.
• RA was converted from degrees to hours.
• VT and BT magnitudes were converted to standard V magnitudes using the formula V = VT - 0.09 * (BT-VT).
• Many data fields, felt to be more or less unneccessary and contributors to excessive catalog size, were trimmed.
