Question
One of my colleagues in the SS Cyg team tried to make an RMF of the Xtend with a spectrum fi le as an input, but the soft"xtdrmf" failed with the error messages below;
> % xtdrmf
> Input PHA fi le with WMAP[q_src.pi]
> Output response fi le[q_src.rmf]
> xtdrmf: ERROR: During main: ahfi ts::getKeyValStr() -> q_src.pi[HDU1]: failed to read header keyword: MTYPE1 [CFITSIO202:
> keyword not found in header]
She looked into the spectrum fi le "q_src.pi" and found the keyword "MTYPE1" was missing, as the software told. We do nhow to resolve this issue. So please help us for creating the RMF fi le for starting our spectral analysis.
The xselect log at the time of generating the spectrum fi le in the question is as follows. The event fi le for input is the one tincluded in the distribution package.
Thank you very much for your help in advance.

Answer
Could you please try HEASFT ver6.34 or Build8 tool ? (or later)
When we tested it with these tools, the process was completed successfully without the xtdrmf error.
We have confirmed that the xtdrmf error is reproduced when the MDB (Mission DataBase) file is incorrect.
The incorrect log (your log) says:
=================
Setting...
Image keywords = X Y with binning = 1
Energy keyword = PI with binning = 1
=================
However, the correct log includes the "WMAP keywords" as follows:
=================
Setting...
Image keywords = X Y with binning = 1
WMAP keywords = DETX DETY with binning = 1
Energy keyword = PI with binning = 1
=================
