Troubleshooting
 

Problem: "I can?t open the script I want to!"

Solution: Make sure the file is a *.csh file. If necessary, change the filter in the Open File Dialog to match the extension of the file to be opened. For example, if the file you want to open is a *.csh file named filename.sh, change the filter to *.sh or *.*.
 

Problem: "I can?t use multiple setup boxes. Why?"

Solution: Multiple setup boxes are only enabled for the Object Only and Object+Lamps calibration modes.
 

Problem: "My echellogram looks strange! The orders seem to have no thickness. What am I doing wrong?"

Solution: You may need to change the slit. In the High Resolution mode, the slits with slitlengths of 12" and 24" are intended to be used. In the Low Resolution mode, the 42" slits are intended to be used.
 

Problem: "I can?t plot some of the transmission curves for some of the filters! Why?"

Solution: Some of filters transmission curves have not yet been determined due to lack of data. The filters for which the Plot Filter Button is enabled have complete data and therefore transmission curves available.
 

Problem: "After using the bad pixel mask for a while, there are a few pixels that have been left behind and are cluttering up the echellogram. How can I get rid of them?"

Solution: The easiest way to redraw the echellogram is to reselect the slit you want to use from the slit dropdown menu. Every time the slit is changed, the echellogram is redrawn. Even if you don?t change the slit, selecting the same slit again will also redraw it, removing any stray marks left over from the bad pixel mask.
