OM Photometry Meeting, Jan. 10, 2001

Agenda and Viewgraphs

• Current photometric calibration
• Description of calculation
• Throughput curves
• Intrinsic accuracy of simulated colour transformation
• Photometric calibration based on ground based observations
• Status of data analysis
• Empirical linearity curve
• procedure to derive linearity curve and photometric transformations
• Accuracy of photometry of revisited stars
• Accuracy of photometry relative to reference star 1
• Accuracy of photometry relative to reference star 2
• Comparison of sky background around each analysed field star (upper: as estimated from sky values, lower: as estimated from the scatter between different exposures.) The scatter is mainly caused by straylight)
• Current implementation of photometry in SAS
• Logic in OM pipeline
• Overview of SAS photometry
• omdetect 1
• omdetect 2
• deblending of sources in omdetect
• Future photometric calibration and SAS implementation
• Identified changes in the SAS/CAL/CCF
