Why do I get this error?

# mkacisrmf (CIAO CIAO 4.2): ERROR: No non-zero pixels map to valid
chip coordinates in the supplied wmap='src.pi[WMAP]' file

The mkacisrmf tool may be used for -110 ACIS data taken on the back-illuminated chips (ACIS-S1 and S3) only.

If the input file contains -110 C data and has the CTI-correction applied but the source is actually on a front-illuminated chip, mkacisrmf fails with an error:

unix% # mkacisrmf (CIAO 4.2): ERROR: No non-zero pixels map to valid
chip coordinates in the supplied wmap='src.pi[WMAP]' file

mkacisrmf infile=CALDB outfile=src.wrmf energy="0.3:11.0:0.01"
channel="1:1024:1" chantype=PI wmap=src.pi"[WMAP]" gain=CALDB
clobber=yes verbose=2 mode=h  failed.

Error: Failed to create RMF for evt2.fits[sky=region(src.reg)]

In this case, the user should be using mkrmf to create the RMF file. Refer to the mkacisrmf thread for more information.
