We describe in detail the extinction correction procedures used for the Beijing‐Arizona‐
Taiwan‐Connecticut Sky Survey (BATC Survey). The survey covers the spectral range 3200 …

This paper summarizes the measurements of astronomical observing conditions with a fixed
pointing to the North Pole over 6 years at the Xinglong Station, where the BATC Multicolor …

The results from work done to extend the Johnson‐Cousins BVRI photometric standard
sequence to faint levels of V∼ 21 mag in compact fields is presented. Such calibration and …

Estimating accurate bolometric fluxes for stars requires reliable photometry to absolutely flux
calibrate the spectra. This is a significant problem for studies of very bright stars, which are …

We have combined multiple nights of charge-coupled device (CCD) observations of NGC
7790, NGC 7006, and NGC 4147 in order to establish a deep sequence of photometric …

We present new observations of two Galactic globular clusters, PAL4 and PAL14, using the
Wide Field Channel of the Advanced Camera for Surveys (ACS) on board the Hubble Space …

The passbands of the Johnson JHKL broadband photometric system used at a number of
major observatories have been compared to the atmospheric window transmissions …

Charge transfer loss on the Wide Field Planetary Camera 2 (WFPC2) onboard the Hubble
Space Telescope is a primary source of uncertainty in stellar photometry obtained with this …

ABSTRACT Recent (1998–1999) absolute spectrophotometry of the night sky over two
southern Arizona astronomical sites, Kitt Peak and Mount Hopkins, is compared to similar …

ABSTRACT A critical analysis and comparison of different methods for obtaining point
spread function (PSF) photometry are carried out. Deep ACS observations of NGC 3370 …
