A cross-calibration between Tycho-2 photometry and Hubble space telescope spectrophotometry.

MAIZ-APELLANIZ J.

Abstract (from CDS):

By analyzing a well-calibrated sample of 256 stars observed with both Hipparcos and HST, I show that Tycho-2 photometry and HST spectrophotometry are accurate and stable enough to obtain a precise cross-calibration. Based on this analysis, I obtain the following photometric zero points with respect to Vega for Tycho-2: 0.020±0.001 (BT-VT), 0.078±0.009 (BT), and 0.058±0.009 (VT).
