gpcal and primary calibrators

[astropete]

hi

for some data being reduced using miriad, i'm using gpcal. when the calibrator is known i get
### Informational: Source is a recognised flux calibrator

when it is not known i get
### Warning: It is unwise to omit OPTION=QUSOLVE when flux is unknown

my problem is that they are both for 1934-638. the second one is listed as B1934-638 so it doesn't know that the data are for the same object.

how should i handle this. is it even a problem?

thanking you in advance

Hi Pete,

probably the best thing to do is to change the source name for B1934-638 back to 1934-638 using uvputhd.

assuming you have split the data into single source file something like this would do the trick:

uvputhd vis=b1934.uv hdvar=source varval=1934-638 out=1934.uv

Cheers,

Mark

"sweet as bro!"

that did the trick. it's easy when you know how.

no, seriously Mark, that was awesome.

thanks very much.
