How to use this page. Input guess for target's polarization parameters: Input I (intensity), f (fractional linear pol.), PA (E-vector PA): I = f = PA = Or input Stokes parameters I, Q, U, V: I = Q = U = V = Give count rate per unit flux from SYNPHOT runs (optional). Input value or leave set to zero. SYNPHOT help. Spectral filter only: Spectral filter + POLQ_PAR: Spectral filter + POLQ_PERP: Give the spectral filter used: F122M F130LP F160BW F165LP F170W F185W F218W F255W F300W F336W F343N F375N F380W F390N F410M F437N F439W F450W F467M F469N F487N F502N F547M F555W F569W F588N F606W F622W F631N F656N F658N F673N F675W F702W F785LP F791W F814W F850LP F953N F1042M FQUVN-A FQUVN-B FQUVN-C FQUVN-D FQCH4N-A FQCH4N-B FQCH4N-C FQCH4N-D LRF If using LRF filter, give wavelength (Ang.): Give the apertures used and the PA_V3 values for each observed image. Optionally, the measured count rate and its uncertainty may be input, and the errors and chi-square will be estimated.
