Bugs: addresp

Bugs fixed in CIAO 4.5

The following is a list of bugs that were fixed in the CIAO 4.5 software release.

The tool SegVs if the phasfile parameter is blank (01 Feb 2012)

unix% addresp infile="" arffile="1.arf,2.arf" phafile="" ...
# addresp (CIAO): ERROR: no inputs of PHA files.

# 27321: Received error signal SIGSEGV-segmentation violation.
# 27321: An invalid memory reference was made.
# 27321: segmentation fault: addresp (1) is:
exit_upon_error->NULL

The output combined RMF file is missing the TLMIN keyword for the F_CHAN column (09 Feb 2012)

The missing keyword means that the RMF cannot be used in Sherpa:

sherpa> load_pha("ngc6300_src.pi")
read ARF file ngc6300_src.arf
ERROR: Failed to locate TLMIN keyword for F_CHAN column in RMF file
'ngc6300_src.rmf'; Update the offset value in the RMF data set to
appropriate TLMIN value prior to fitting 
read RMF file ngc6300_src.rmf

Workaround:

Add the missing keyword with dmhedit. The F_CHAN column has TLMIN4=1 for Chandra RMFs:

unix% chmod +w ngc6300_src.rmf
unix% dmhedit ngc6300_src.rmf f="" key=TLMIN4 op=add value=1
