The results:

• Page 1 and 2: system performance
• page 1 has all of the points
• page 2 has excluded points where one or more tiedowns lost tension
• Top frame: gain K/Jy
• 2nd frame: Tsys . this is stokes I
• The polA,polb temps are about 26, and 50 K.
• 3rd frame: SEFD (Tsys/gain) in Jy.
• bottom: average beam width in Arc seconds.
• Page 3 and 4. pointing errors vs za and az
• page 3 has all points
• page 4 excludes points with no tension in 1 or more tiedown cables
• Top: za Errror vs za
• 2nd: za Error vs az
• 3rd: az error vs za
• bottom: az error vs az
• comments:
• B1140
• at transit the az error got large probably because of the slew rate
• The platform for a little low during this source (tiedown tracking was off). this would give a negative za error.
• Page 5: compare source track on 2 days to check  pointing repeatability
  
• B1328+254 was tracked on 18 and 22may20. It has the dec closest to venus for the may20
• Points with no tiedown tension have been excluded
• Black is 18may20, red is 22may20
  
• Top: zaError vs za
• Bottom: az error vs za
• The main contributor to the pointing error not repeating is probably the temperature variation.
• The tiedowns should correct for the temperature variation if the distomats are able to measure the position of the platform.
• On 18may20 the distomats were not completing their measurements.
  
• The   Average pointing error for the runs are:
• 
  

• 	za err Asecs		az err Asecs
  	avg	rms	avg	rms
  all points	-3.1	13.7	-1.7	8.2
  exclude no tension points	0	6.1	-.3	8.1

Comments:

• The venus runs will be during the day.
  
• When the source rises and sets there can be a large pointing error (30-60 asecs depending on the air temperature) from the loss of tension in the tiedowns.
