OPTIONS /TEMPLOAD
/TEMPLOAD tempColdLoad tempAmbientLoad

/TEMPLOAD * ...
Set effective temperatures for the calibration loads at cold and ambient
temperature.
Real :: tempColdLoad !
Real :: tempAmbientLoad !
NEW LOGIC FOR SINGLE-PIXEL SIS RECEIVERS (FROM SUMMER 2007, paKo v1.0.7)
If a numerical value is entered for tempColdLoad or tempAmbientLoad,
that value is used for calibration calculations.
Instead of specifying a value one may enter the string L(OOKUP) for
tempColdLoad and/or tempAmbientLoad. This is shown in the pakoDisplay
by the letter "L" instead of a number.
In this case, during the execution of the observations, the NCS will
use the "best-known" values for the corresponding load temperature(s).
For tempColdLoad this is based on a lookup table, for tempAmbientLoad
it is derived from a measurement of the physical temperature.
The lookup table for tempColdLoad normally is valid for the standard
calibration system with a closed-cycle cooling system.
A * can be substituted for tempColdLoad, which means to leave the
value for tempColdLoad unchanged from the previous RECEIVER command.
IF THE OBSERVERS HAVE ANY DOUBT ABOUT THIS, THEY SHOULD ASK A RECEIVER
ENGINEER FOR THE CORRECT VALUE AND ENTER IT EXPLICITLY.
NOTE: FOR HERA The new logic is not yet available. However, for HERA
"best-known" values are always used during the execution of the
observations. This is the same logic as in pevious versions of paKo/NCS.
