WISE Software Interface Specification; PCOV_rex10; (WSDC D-I161) SIS Written by Howard McCallon, version 1.0, 07/23/2009 Interface Name: PCOV (Parameter Covariance file) Type of Interface: ASCII file in IPAC table format Read By: Off-line Analysis Program (TBS) ..................... J.W. Fowler/ H.L. McCallon Written By: PRex/SFPRex (Single-Frame Position REconstruction) .. H.L. McCallon/ J.W. Fowler DESCRIPTION One PCOV file is generated for each frameset and includes the elements of the 20x20 covariance matrix generated by fsfitr in SFPRex. For convience the final fit parameters are also included as key words. The first three parameters in each band are in units of arcseconds and the last two are unitless. Therefore nuits on an individual covariance matrix element will be asec-sq, asec or unitless, depending on the parameter combination. Key words and column headers are described in the file itself. The PCOV file has been added to allow MFPRex to include correlations while assigning uncertainties when longer wavelength bands are computed from the shortest wavelenght band solution. Without this information the uncertainties on the longer wavelength bands would be unrealistically large.
