    I am doing GMOS IFU data reduction by using pyraf, and there is a problem in gfextract task(same thing happens even when using iraf) :

    IrafError: Error running IRAF task imcopy
    IRAF task terminated abnormally
    ERROR (808, “Pixel subscript out of bounds (tmppaste6662_61[SCI,1][1:3139,1:4176])”)

    This error does not occur when I try the same task to 2006, 2015 data, only 2019 programs’ files give this error. I think it results from difference of vertical size(2019 data has 4176 pixels in y axis, but 2006 & 2015 data has 4608) but I don’t know the exact reason.

    Any ideas or advice will be greatly appreciated.

    I have the same problem with 2020 data.
    Did you find any way to work around this?

    Possible causes:

    * you are using a old version of Gemini IRAF that does not know about the new GMOS-N Hamamatsu CCD that were put in in March 2017. Solution: update Gemini IRAF. https://www.gemini.edu/observing/phase-iii/understanding-and-processing-data/data-processing-software/download-latest (Install the Python 2.7 version since PyRAF doesn’t work well with Python 3)

    * Your reference file does not match in size.

    * Your response file does not match in size.
