What it really is:

Find the index (I) that is closest to motor position Then K=93-I IF(K.LT.0) K=93-K I=K/10 Position 11 => CHAR(65+I) # 65 is an upper case 'A' Position 12 => K - 10*I # (goes from 0 to 9)

/!\ J4 and up are "super focus" positions. A0 to J2 are nominal positions.

Here is the source from PROCESS_FITS.f:

IF(NC.EQ.3) THEN NQ=FLT K=0 DO I=116,0,-1 IF(NQ.LE.STEP(I+1)) K=93-I ENDDO IF(K.LT.0) K=93-K I=K/10 K=K-10*I PICNM(11:11)=CHAR(65+I) FLT=K ENDIF... WRITE(PICNM(12:12),FMT='(I1)') FLT

NavCam (CAMERAID = 4)

FLT = 0

NFTCam (CAMERAID =5)

FLT = 0

Everything is the same except for Character Position 11

PolyCam

PICNM(11:11)=CHAR(ICHAR(PICNM(11:11))+13)

MapCam, NavCam, etc.
