NUMBER: 310 MODULE: daophot.psf SYSTEM: V2.10 DATE: Mon Aug 28 08:55:09 MST 1995 FROM: davis BUG: Using the 'd' or ':d' keystroke commands will cause a segmentation violation on Solaris systems and may cause problems on other systems, although apparently not on SunOS systems. The problem was caused by a subroutine which was being called with an unused output variable set to a constant STATUS: Fixed for the next release of iraf. One possible workaround is to fit the psf with the 'f' keystroke command and then use the 's' or ':s' keystroke command to examine and optinally delete the star. NUMBER: 463 MODULE: splot SYSTEM: V2.11-V2.11.3a DATE: Tue Feb 15 15:59:39 MST 2000 FROM: valdes BUG: The 'h' key method for measuring equivalent widths will produce an arithmetic exception (such as divide by zero) when the pixel coordinate becomes large (say > 4000). The exact error and limit value depends on the host system. The workaround is to extract the desired piece of the spectrum into a shorter piece. If you know the pixel coordinates you could use IMCOPY with an image section. If you know the wavelength region then use SCOPY. on> imcopy longspec[5210:5310] temp or on> scopy longspec temp w1=6140 w2=6143 rebin- on> splot tempAlternatively one can use one of the other methods for measuring equivalent widths such as 'e', 'k', or 'd'. STATUS: The algorithm is revised in the next release.
