Automatic research script

Post by VAastro » 26 Jan 2020, 16:23

Hi,

I want to be able to enter an object list for automatic image control:

Object name, RA.Dec, no of filter"X" exposures, "X" filter exposure time,no of filter "Y" exposures,"Y" filter exposure time,no of filter "Z" exposures, "Z" filter exposure time,...etc.

Can the Telescope.List function be modified?

Thanks
Erik

Hi,
this task is done by other users, but they don't use the Telescope List. You need to create your own text database, then read that file in your script and use the data. If you write more information about your research I can give a better suggestion about the procedure and the script.

Thanks Fabio

Here is example of my list

"V2301 Oph" 18 00 35.5 +08 10 13.9,V,4,30,I,4,15,B,6,45
"EP Dra" 19 07 06.2 +69 08 44.0,V,4,30,I,4,30,B,5,60
"PGIR19brv" 21 09 25.53 +48 10 52.2,V,2,10,I,2,15,B,6,30

Where V,I and B are filter wheel positions

I am not sure how to read this text database in my script.

Thanks
Erik

I suggest to separate fields by spaces, it's much easier. For example:

Code: Select all

Name        Ra          Dec          V     I     B
V2301 Oph   18 00 35.5  +08 10 13.9  4 30  4 15  6 45
EP Dra      19 07 06.2  +69 08 44.0  4 30  4 30  5 60
then if you want to have a free format (any number of chars and spaces) here is a test script:

Code: Select all

s = "V2301 Oph   18 00 35.5  +08 10 13.9  4 30  4 15  6 45"
print s
print Parse(s, 4)
print Parse(s, 5)
print Parse(s, 6)
decl = SexagToDecim(Parse(s,4) , Parse(s,5) , Parse(s,6))
print decl
print DecToString(decl)

function Parse(line, v)
  c1 = 13
  c2 = Len(line)
  res = ""
  for i = c1 to c2
     if line[i] = " " then continue
     if line[i-1] = " " then v = v-1
     if v = 0 then res = res + line[i]
  next i
  resNum = Val(res)
  if res <> "" and resNum = 0 and res[1] = "-" then resNum = -1.0E-12
  return resNum
end function

function SexagToDecim(d,m,s)
  decim = Abs(d) + m/60 + s/3600
  if d < 0 then decim = -decim
  return decim
end function

If instead you prefer a fixed text format, you can use the Mid function:

Code: Select all

123456789012345678901234567890123456789012345678901234567890
Name        Ra          Dec          V     I     B
V2301 Oph   18 00 35.5  +08 10 13.9  4 30  4 15  6 45
EP Dra      19 07 06.2  +69 08 44.0  4 30  4 30  5 60

RaH = Mid(s, 13, 2)
RaM = Mid(s, 16, 2)
etc.. 
In any case be careful about the " -00 " declination.
To open the file use the command OpenText(filename).
