More PSFs (Obtained November 1992) The PSFs in this directory are in general very high S/N, i.e. several 1000's of counts in the peak. To achieve these S/N levels, the exposures were taken in the 256x256 format which allows much higher peak count-rates to be used. The price we have to pay for the high S/N is that some slight truncation of the PSFs occurs at radii > 2.5-3", how- ever I think most people will agree that this price is reasonable. P.S. The phrase of the year is: "OTA Breathing". (This is a 'Gentle Reminder' that breathing effects by the OTA significantly alter the PSF from one image to the next.) ============================================================ This following is info on PSF files found in this directory. f120m ROOTNAME = X15P0202T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F120M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f130lp ROOTNAME = X15P020AT FILTNAM1 = F6ND FILTNAM2 = CLEAR2 FILTNAM3 = F1ND FILTNAM4 = F130LP PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f130m ROOTNAME = X15P0203T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F130M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f140m ROOTNAME = X15P0102T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F140M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f140w ROOTNAME = X15P0103T FILTNAM1 = CLEAR1 FILTNAM2 = F140W FILTNAM3 = F1ND FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f152m ROOTNAME = X15P0104T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F152M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f165w ROOTNAME = X15P0204T FILTNAM1 = F4ND FILTNAM2 = CLEAR2 FILTNAM3 = F165W FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f170m ROOTNAME = X15P0105T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F170M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f175w ROOTNAME = X15P0106T FILTNAM1 = F2ND FILTNAM2 = F175W FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f190m ROOTNAME = X15P0205T FILTNAM1 = F2ND FILTNAM2 = CLEAR2 FILTNAM3 = F190M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f195w ROOTNAME = X15P0107T FILTNAM1 = F4ND FILTNAM2 = CLEAR2 FILTNAM3 = F195W FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f210m ROOTNAME = X15P0206T FILTNAM1 = F2ND FILTNAM2 = CLEAR2 FILTNAM3 = F210M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f220w ROOTNAME = X15P0207T FILTNAM1 = F4ND FILTNAM2 = F220W FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f231m ROOTNAME = X15P0108T FILTNAM1 = F2ND FILTNAM2 = CLEAR2 FILTNAM3 = F231M FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f253m ROOTNAME = X15P0109T FILTNAM1 = CLEAR1 FILTNAM2 = CLEAR2 FILTNAM3 = F1ND FILTNAM4 = F253M PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f275w ROOTNAME = X15P010AT FILTNAM1 = F2ND FILTNAM2 = F275W FILTNAM3 = F1ND FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f307m ROOTNAME = X15P010BT FILTNAM1 = F2ND FILTNAM2 = CLEAR2 FILTNAM3 = CLEAR3 FILTNAM4 = F307M PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f320w ROOTNAME = X15P0208T FILTNAM1 = F6ND FILTNAM2 = F320W FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f370lp ROOTNAME = X15P010DT FILTNAM1 = F4ND FILTNAM2 = F370LP FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f600m ROOTNAME = X15P010CT FILTNAM1 = F600M FILTNAM2 = CLEAR2 FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256 f630m ROOTNAME = X15P0209T FILTNAM1 = F630M FILTNAM2 = CLEAR2 FILTNAM3 = CLEAR3 FILTNAM4 = CLEAR4 PXFORMT = NORMAL SAMPOFF = 0.3840000E+03 LINEOFF = 0.3840000E+03 SAMPPLN = 256 LINEPFM = 256
