NUMBER: 140 MODULE: dataio.rfits SYSTEM: V2.9 DATE: Thu Dec 6 11:38:42 MST 1990 FROM: davis BUG: A command of the form 'rfits mta 1-8 '' oldirafname+' will generate the message 'ERROR: T_RFITS: Error reading output file name' because the code was not dealing properly with an empty output file list. STATUS: Rfits has been modified in 2.10 so that a temporary output file name is created if oldirafname is true or a clear error message is generated if oldirafname is false, and the user has set the output file name to ''. The workaround is to avoid setting the output file name to ''. 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.
